Abstract: Recent developments in computer and communication technologies are leading to an increasingly networked and wireless world. In the context of networked control systems and cyber-physical systems this raises new challenging questions, especially when the computation, communication and energy resources of the system are limited. To efficiently use the available resources it is desirable to limit the control actions to instances when the system really needs attention. Unfortunately, the classical time-triggered control paradigm is based on performing sensing and actuation actions periodically in time (irrespective of the state of the system) rather than when the system needs attention. Therefore, it is of interest to consider event-triggered control as an alternative paradigm, as it seems much more natural to trigger control actions by well-designed events involving the system’s state, output or other available information, i.e., bringing feedback in the sensing and actuation processes.
 
In this talk, we discuss the challenges and recent advances of event-triggered control focusing on two main design approaches: Lyapunov-based designs and optimization-based methods. Main results regarding control-related properties such as stability, performance and robustness are provided, next to guarantees on the existence of a positive lower bound on the inter-event/transmission times (minimal inter-event times).  Clearly, the latter is essential from an implementation point of view and the side of utilization of the computation, communication and energy resources. Comparisons to periodic time-triggered control, and other resource-aware controllers such as self-triggered control will be provided. Various applications including experiments performed on a platoon of vehicles will be presented.

Bio: Maurice Heemels received the M.Sc. degree in mathematics and the Ph.D. degree in control theory (both summa cum laude) from the Eindhoven University of Technology (TU/e), the Netherlands, in 1995 and 1999, respectively. From 2000 to 2004, he was with the Electrical Engineering Department, TU/e and from 2004 to 2006 with the Embedded Systems Institute (ESI). Since 2006, he has been with the Department of Mechanical Engineering, TU/e, where he is currently a Full Professor. He held visiting professor positions at the Swiss  Federal Institute of Technology (ETH), Switzerland (2001) and at the University of California at Santa Barbara (2008). In 2004, he worked also at the company Océ, the Netherlands. His current research interests include hybrid and cyber-physical systems, networked and event-triggered control systems and constrained systems including model predictive control. Dr. Heemels served/s on the editorial boards of Automatica, Nonlinear Analysis: Hybrid Systems, Annual Reviews in Control, and IEEE Transactions on Automatic Control. He served/s as the general chair of the IFAC Conference on Analysis and Design of Hybrid Systems (ADHS) 2012, the IPC chair of the IFAC workshop on Distributed Estimation and Control in Networked Control (NECSYS) 2013, the IPC co-chair of the European Control Conference 2013, and the IPC chair of IFAC Conference on Analysis and Design of Hybrid Systems (ADHS) 2018.
He was a recipient of a personal VICI grant (1.5 Meuro) awarded by STW (Dutch Technology Foundation). He is a Fellow of the IEEE.
