Keynote 1: 

Modern Sliding Mode Control with Application to Connected and Automated Vehicles

 

Prof. Antonella Ferrara 

(IEEE Fellow)

University of Pavia, Italy

Abstract

Sliding Mode Control is a nonlinear control methodology based on the use of a discontinuous control input which forces the controlled system to switch from one structure to another, evolving as a variable structure system. This structure variation makes the system state reach in a finite time a pre-specified subspace of the system state space where the desired dynamical properties are assigned to the controlled system. In the past years, an extensive literature has been devoted to the developments of Sliding Mode Control theory. This kind of methodology offers a number of benefits, the major of which is its robustness versus a significant class of uncertaintiesduring the sliding mode. Yet, it presents a crucial drawback, the so-called chattering, which may disrupt or damage the actuators and induce unacceptable vibrations throughout the controlled system. This limits the practical applicability of the methodology, especially in case of mechanical or electromechanical plants. This drawback has been faced by the theoretical developments of the last two decades. They will be reviewed in this talk, illustrating how the “modern” results can beprofitably used to solve practical control problems in complex systems as the automotive ones. The talk will develop starting from single vehicle control and coming to discuss formation control of fleets of connected and automated vehicles (CAVs), with the aim of producing a beneficial impact on road traffic..

Keynote 2: 

Privacy and safety in cyber-physical systems

 

Prof. Dimitri Lefebvre

University of Le Havre Normandie, France 

Abstract

In recent years, the tremendous growth of computer technology has led to the proliferation of highly complex cyber-physical systems, in particular in Industry 4.0 and Internet of Things. Such systems exhibit behaviors determined by the asynchronous occurrence of certain events and are termed Discrete Event Systems(DES). Examples of DES are encountered in many traditional application domains, such asautomated manufacturing, computer networks, transportation, as well as inemerging areas like healthcare, or management of technical, human and financial resources.

A significant research effort has been devoted to DES in order to address a series of difficult problems that are often combinatorial in nature, and require advances methodologies The aim of this talk is first to give some basic modeling notions to represent DES in order to address a large variety of problems for cyber-physical systems. Then, some privacy,and safety issues arediscussed.On one hand, opacity is presented to increase privacy and cyber-security. On the other hand, fault diagnosis illustrates how it is possible to detect and isolate some faults in the system based on its observations. Performance evaluation is introduced to provide a detailed analysis of such properties.

Finally, a list of open questions and future challenges is proposed.
