Confirmed Invited Talks
On fractional derivatives and systems
Manuel Duarte Ortigueira
Electrical Engineering Department of the Faculty of Science and Technology of Universidade Nova de Lisboa.
Abstract: Fractional behavior is ubiquitous. In fact, many natural and man-made systems exhibit a fractional behavior that can be observed from several representations. The most important are the “power law”, the “long range dependence”, and the “non 20-dB increase/decrease” in Bode diagrams. This will be illustrated with some examples.
To obtain correct mathematical formulations for modelling such systems, the fractional derivatives are required. In order to avoid the difficulty of introducing many derivative formulations, a heuristic approach will be followed in order to obtain derivatives with a full agreement with classic results that will emerge as particular cases.
The fractional linear systems will be presented and a brief study will be done.

What Authors Should Know to Successfully Publish Papers in Good Journals
Department of Electrical and Computer Engineering University of Louisville, Louisville, Kentucky 40292, USA.
Abstract: Since different publication formats are designed to reach various audiences, they often undergo different review procedures, and have widely different impact. Ultimately, however, papers and publications are judged by their relevance, readership and citations they acquire. Bibliometric impact measures for journals and for individuals as expressed by Impact Factor and other indicators are reviewed and compared for major journals in different subject areas. Forward citation trees provided by ISI/Web of Science are reviewed as ultimate examples of authors’ achievement. Open Access publishing paradigm is also discussed. By comparing the perspectives of authors, readers and editors, this seminar offers ample guidelines for reviewing, but mostly for preparing, writing and publishing successful technical papers. Practical guidance for authors is also covered as well as ethical aspects of publishing.

Optimization & Decision Making in Intelligent Urban Transportation Systems
Abdelkader El Kamel
Ecole Centrale de Lille, France
Abstract: This plenary talk is concerned with the application of intelligent control theory in the future road transportation systems. With the development of human society, the demand for transportation is much stronger than any other period in history. More flexible and more comfortable, private cars are preferred by many people. Besides, the development of automobile industry reduces the cost to own a car, thus car ownership has been growing rapidly worldwide, especially in major cities. However, the increase of car number makes our society to suffer from traffic congestions, exhaust pollution and accidents. These negative effects force people to find ways out. In this context, the concept of “Intelligent Transportation Systems (ITS)” is proposed. Scientists and engineers have been working for decades to apply multidisciplinary technologies to transportation, in order to make it closer to our vision, such as safer, more efficient, more effort saving, and environmentally friendly.
One aspect is (semi-)autonomous systems. The main idea is to use autonomous applications to assist/replace human operation and decision. Advanced driver assistance systems (ADAS) are designed to assist drivers by alerting them when danger (e.g. lane keeping, forward collision warning), acquiring more information for decision-making (e.g. route plan, congestion avoidance) and liberating them from repetitive and trick maneuvers (e.g. adaptive cruise control, automatic parking). In semi-automatic systems, driving process still needs the involvement of human driver: the driver should set some parameters in the system, and he/she can decide to follow the advisory assistance or not. Recently, with the improvement of sensing technology and artificial intelligence, enterprises and institutes have been committed to the research and development of autonomous driving. In certain scenarios (e.g. highways and main roads), with the help of accurate sensors and highly precise map, hands-off and feet-off driving experience would be achieved. Elimination of human error will make the road transportation much safer, and better space utilization will improve the usage of road capacity. However, autonomous cars still need driver’s anticipation in certain scenarios with complicated traffic situation or limited information. The inner layout of autonomous cars would not be much different from current cars, because steering wheel and pedals are still necessary. The next step of autonomous driving is driver-less driving, in which the car is totally self-driven. The seat dedicated for driver would disappear and people on board would focus much. The car-sharing economy behind driverless cars would be enormous: in the future, people would prefer calling for a driver-less car when needed to owning a private car. Thus congestions and pollutions could be relieved.
Another way is cooperative systems. Obviously, the current road transportation notifications are designed for human drivers, such as traffic lights, turning lights and road side signs. The current autonomous vehicles are equipped with cameras dedicated to detect these signs. However, notifications designed for humans are not efficient enough for autonomous vehicles, because the usage of camera is limited by range and visibility, and algorithms should be implemented to recognize these signs. If the interaction between vehicles and environment is enabled, the notifications can be delivered via V2X communications, thus vehicles can be noticed in larger distance even beyond the sight, and the original information is more accurate than the information detected by sensors. When the penetration rate of driver-less cars is high enough, it would not be necessary to have physical traffic lights and signs. The virtual personal traffic sign can be communicated to individual vehicles by the traffic manager. In cooperative systems, an individual does not have to acquire the information all by its own sensors, but with the help of other individuals via communication. Therefore, autonomous intelligence can be extended into cooperative intelligence.
We will focus on the development of applications to improve the safety and efficiency for intelligent transportation systems in context of autonomous vehicles and V2X communications in the scope of cooperative systems. Control strategies are designed to define the way in which the vehicles interact with each other and with infrastructures. The main aspects which will be discussed are summarized by:
- A PSO (particle swarm optimization)-based platoon control algorithms for following vehicles in platoons. Constraints like control input, engine power and maximum speed are considered when designing the cost function. It is an attempt of applying bionic optimization algorithm in vehicular platoon control. The parameters are regulated to response to potential real-time usage in the future.
- Cooperative Adaptive Cruise Control in Vicinity of Intersections (CACC-VI) to improve the intersection’s throughput by taking advantage of the “opportunity space” on road. The vehicular platoons are reorganized to accelerating platoon and decelerating platoon based on vehicles’ dynamic abilities.
- For intersections without crosswalk, there are no other individuals but vehicles. In this case, except traffic lights, there can have some other management methods with the help of V2X communications. Decentralized Autonomous Intersection Control (DAIC) is designed for light traffic situations, to control vehicles to get through the intersection with no collision and less delay. Before arriving at the intersection, a vehicle demands the space-time occupancy situation from the intersection manager, and based on the motion of the preceding vehicle, it will adjust its own velocity to a collision-free value and it should maintain this velocity until fully getting through the intersection. Basically, DAIC is an enumerative negotiation-based method. A simulation testbed to test the intersection control algorithm is designed in UML then realized by the combination of
- Matlab and a traffic simulator SUMO.
- Trajectory Planning based Autonomous Intersection Management (TP-AIM) for all traffic densities is presented. Based on the occupancy information from the manager, the vehicle searches for safe entering windows. And according to these windows and the future motion of the preceding vehicle, a dynamic programming based method is used to plan the vehicle’s trajectory. The related communication procedure is also described. Compared to traditional and adaptive traffic lights, the efficiency of TP-AIM is greatly improved. The principle of TP-AIM could be used in different types of intersections even in heavy traffic conditions.

Human-robot collaboration for smart factories
Centre for Research and Advanced Studies (CINVESTAV, Mexico). Robotics and Advanced Manufacturing Department
Abstract: Industrial robots are reliable machines for manufacturing tasks such as assembly, welding, painting and palletizing operations. They have been traditionally programmed by an operator using a teach pendant in a point-to- point scheme with limited sensing capabilities such as industrial vision systems and force/torque sensing. Today, industrial robots can react to environment changes specific to their task domain but are still unable to learn skills to effectively use their current knowledge. The need for such a skill in unstructured environments where knowledge can be acquired and enhanced is desirable so that robots can effectively interact in multimodal real-world scenarios.
In this paper, an alternative approach based on Artificial Neural Networks to embed and effectively enhance knowledge into industrial robots working in manufacturing scenarios is reviewed. During learning, the robot uses its sensorial capabilities resembling a human operator to successfully accomplish the requested operation in assembly and welding. Current work, issues and experiments are presented and future work envisaged regarding learning in distributed systems in smart factories involving human-robot interaction.

Data Management Support for moving-object data
M. Andrea Rodríguez
Department of Informatics Engineering and Computer Science at the University of Concepcion, Chile.
Abstract: Due to the current advances in sensor networks, wireless technologies, and RFID-enabled ubiquitous computing, data about moving-objects (also referred as trajectories) is an example of massive data relevant in many real applications. Think in the notion of Smart Cities, which implies the use of information and communication technologies in combination with social and human capital to enhance the quality of life of a community. In this context, the optimization of the transportation systems by control surveillance, road planning, and road navigation systems are of special relevance. Trajectories can be reconstructed from, for example, modern cellular phones with GPS devices or from smartcards (that users can recharge with money) of public transportation systems. In this presentation, I cover past and current research efforts addressing the modeling and processing of moving object data. I review data models to represent where and when objects have been or will be. I consider for query processing the main types of queries and data structures and state the challenging issues of our current research.

Department of Electronic Engineering, Universidad Técnica Federico Santa María, Valparaíso, Chile. Previously with the Centro de Investigación en Nanotecnología y Materiales Avanzados (CIEN-UC), Department of Electrical Engineering, Pontificia Universidad Católica de Chile (PUC), Santiago, Chile
Abstract: Resistive switching electronic devices (ReRAM devices or memristors) have been known ever since the 60s. However, owing to the physical realization of the Chua’s memristor by the Hewlett-Packard Laboratories in 2008, new research tracks and trends in modern circuit design have indeed been created. The memristor, a nanoscale, nonvolatile, two-terminal resistive device whose resistance changes depending on the input signal applied to its terminals, is currently being explored for several emerging applications regarding upgraded and novel, energy-efficient digital/analog implementations such as nonlinear (chaotic) circuits, storage systems, logic circuits, neuromorphic and generally unconventional circuit architectures. This talk covers a timely topic of academic and industrial interest, aiming to stimulate further research on memristive devices, circuits, and systems. It particularly considers the design and development of nanoelectronic circuits, systems and computing architectures focusing on memristor as the main storage and computing element. The ultimate goal is to explore and report the major related challenges and present state-of-the-art research directions for the smooth transition from conventional circuit technologies to emerging, beyond von Neumann computing nanotechnologies. The presented material spans from fundamental device modeling to emerging, dense, multi-level storage system architectures and novel, unconventional circuit design methodologies, targeting advanced analog/digital, massively parallel, neural-based computational and learning structures.

HVDC Grids and Renewable Energy Integration
Department of Systems Engineering and Control, Technical University of Valencia, Spain
Abstract: Renewable Energy is a key contributor to fight climate change. Latest bids in Europe and elsewhere have shown that renewable energy can be provided at competitive market price. Even some of the new off-shore wind power plants to be installed in the North Sea will operate without any subsidies, competing directly in electricity markets with other sources of energy.
Nevertheless, there is a continuous drive to make bulk wind energy and other renewable energy sources more and more competitive. Substantial research is taking place to reduce the total cost of electricity generated by off-shore wind farms.
A key component is the reduction of grid connection and transmission costs. High Voltage DC connections are used for the connection of large off-shore wind farms and large electric systems. This kind of links are paramount to bring large amounts of electricity across large distances. Therefore, both cost reduction and increase on reliability are constant drivers for more advanced HVDC technology.
This talk will address the following topics:
- Technical hurdles for high penetration of renewable energy.
- State of off-shore wind farms in Europe.
- State-of-the-art HVDC connection technologies.
- Power Electronics and their control for the connection of off-shore wind farms using HVDC links, including diode rectifiers.
- European research on meshed HVDC grids.

Control challenges in dealing with Cyber-Physical Systems
Instituto Universitario de Automática e Informática Industrial, Universitat Politècnica de València, Spain
Abstract: A cyber-physical system integrates computing, communication and storage capabilities within entities in the physical world. Traditionally, control designers and real-time computer and telecommunication experts work separately. The first conceive the control algorithms based on the required performance and the process knowledge, regardless their subsequent implementation, whereas the computer experts deal with the control code without paying much attention to the impact of the code execution in the control performance, and the communication experts provide the link, assuming data accessibility and validity. But they are interlaced and the full design should be jointly treated, mainly if the control tasks share resources with some other activities and these resources are limited. In this talk, the real-time control design and implementation will be reviewed, mainly from the control perspective.
Global requirements in control applications in time critical environments, such as automobile, aerospace or flight control, where multiple interactive control loops are implemented, are reviewed. Special attention is devoted to new and widespread control scenarios where the controller is not anymore implemented in a full dedicated computer without resources constraints, but sharing and competing for computing, storage and communication facilities with several other tasks. Embedded control systems, networked control systems and event-based control systems challenge the design of the control and its implementation where architectural issues play a relevant role in the controlled system performance. Some key concepts interacting with both, the control performance and the control implementation, such as the control effort or the control kernel are emphasized and some general directions in the co-design are summarized.
