Self-triggered and event-triggered control are recently
proposed control paradigms that abandon the conventional
periodic sampling of outputs and updating of control
values with the objective to reduce the utilization of
communication resources, while still guaranteeing
desirable closed-loop behaviour. Self-triggered and
event-triggered control consist of two elements, namely a
feedback controller that computes the next control input,
and a triggering mechanism that determines what the next
control update time will be. In this presentation the
focus will be on design methodologies for unconstrained
and constrained discrete-time linear systems with
guaranteed performance in terms of chosen cost functions.
In particular, the resulting control laws will possess
three important features. First of all, the control law is
designed such that a priori chosen (sub)optimality levels
are guaranteed next to asymptotic stability and constraint
satisfaction. Secondly, it offers one of the first
approaches, which addresses the joint design of both the
feedback controller and the triggering mechanism. Thirdly,
it realizes significant reductions in the usage of network
resources and avoids bursts in communications. These
beneficial features and various implementation aspects
will be presented in detail. Connections to MPC will be
established. If time allows also model-based versions that
do not require full state information will be provided.
Biographical Information
Maurice Heemels received the MSc degree in
mathematics (with highest distinction) and the Ph.D.
degree in system and control theory (summa cum laude) from
the Eindhoven University of Technology (TU/e), Eindhoven,
the Netherlands, in 1995 and 1999, respectively. From 2000
to 2004, he was with the Electrical Engineering
Department, TU/e, as an Assistant Professor and from 2004
to 2006 with the Embedded Systems Institute (ESI) as a
Research Fellow. Since 2006, he has been with the
Department of Mechanical Engineering, TU/e, where he is
currently a Full Professor in and chair of the Hybrid and
Networked Systems Group. He held visiting research
positions at the Swiss Federal Institute of Technology
(ETH), Zurich, Switzerland (2001) and the University of
California at Santa Barbara (2008). In 2004, he was also
at the Research & Development laboratory, Océ,
Venlo, the Netherlands. His current research interests
include hybrid dynamical systems, networked and
event-triggered control systems and constrained systems
including model predictive control. Maurice is a recipient
of a VICI innovation grant from the Netherlands
Organization for Scientific Research (NWO) for research in
the area of wireless control systems. He serves as an
Associate Editor for the journal Automatica and served as
an Associate Editor for Nonlinear Analysis: Hybrid
Systems. He is general chair of the 4th IFAC Conference on
Analysis and Design of Hybrid Systems 2012, IPC co-chair
of the European Control Conference 2013, and IPC chair of
the 4th IFAC Conference on Distributed Estimation and
Control in Networked Systems 2013.
