In event-triggered control systems, the times when the sensors are sampled, and the control input is updated can be selected based on state or output information. This can potentially enhance standard digital control systems where the sampling period is fixed. This talk aims to answer if this is the case for the traditional Linear Quadratic Gaussian and l2-gain problems. In the periodic sampling case, these two problems can be framed in the h2 and hinf design framework, respectively, and the optimal control policies and resulting performances are well-known. This talk discusses how in the Linear Quadratic Gaussian settings, one can design event-triggered control policies that strictly outperform optimal periodic designs, and even quantify such a performance gain. On the other hand, in the l2-gain setting, one can design event-triggered controllers that guarantee the same optimal l2-gain of periodic controllers, but not a strictly lower l2-gain. The concepts are illustrated with numerical examples.


Biographical Information

D. J. (Duarte) Antunes was born in Viseu, Portugal. He received the Licenciatura in Electrical and Computer Engineering from the Instituto Superior Técnico (IST), Lisbon, in 2005. He did his PhD (cum laude) from 2006 to 2011 in the research field of Automatic Control at the Institute for Systems and Robotics, IST, Lisbon, in close collaboration with the University of California, Santa Barbara. From 2011 to 2013, he held a postdoctoral position at the Eindhoven University of Technology (TU/e). He is currently an Assistant Professor at the Department of Mechanical Engineering at TU/e. He is a Senior Member of IEEE, Associate Editor of IEEE Transactions on Automatic Control and IEEE Control Systems Letters, and co-author of the papers that received the IEEE Control Systems Letters Outstanding Paper Award 2018, the best paper award at the IEEE International Conference on Event-based Control, Communication and Signal Processing 2017, and the best student paper award in the 17th IFAC Symposium on Automatic Control in Aerospace 2007. His research interests include networked control systems, stochastic control, approximate dynamic programming, and robotics.
