Abstract

In this paper, we investigate the problem of <formula><tex>$regulating$</tex></formula> a continuous-time linear time invariant (LTI) system to a desired point using <formula><tex>$discrete event$</tex></formula> measurements from signal change detection sensors with a logarithmic event generation threshold (trigger), which includes the recently developed neuromorphic vision sensors. Existing control algorithms typically only process periodic measurements and so a new class of algorithms needs to be developed that can efficiently process the sensors&#x0027; <formula><tex>$asynchronous$</tex></formula> discrete events for control tasks. Thus, we present a novel control design procedure that <formula><tex>$regulates$</tex></formula> the hybrid system, consisting of the continuous LTI system and a discrete-event signal change observation model, to a desired set-point. Moreover, we provide the set of thresholds (sufficient conditions) for the given system to fulfill the regulation task. The effectiveness of our approach is illustrated on an unstable system.
