On Minimum-Variance Event-Triggered Control
Abstract
Conventional sampled-data feedback systems use time-triggered sampling mechanisms. Triggering sampling instances on events, e.g. on sufficiently large deviations from expected behavior, is conceptually appealing, but technically more challenging. There are not many event-triggering schemes that can guarantee to outperform optimal time-triggered controllers under comparable communication demands. One exception is the Lebesgue sampling algorithm of Åström & Bernhardsson (1999), which is proved to outperform the conventional optimal smpled-data LQG by a factor of 3 for a single integrator process.
In this talk I'll discuss some extensions of the Lebesgue scheme to more general, and more practical, LQG settings. In particular, a separation between the controller architecture and the event generation algorithm will be proved and exploited.
The seminar presents a joint work with Alexander Goldenshluger from U Haifa. Remarkably, this collaboration on stochastic event-triggered control was triggered by two deterministic events that took place long time ago in the city of Frunze.
