This article addresses the event-triggered control design for stabilization of Lipschitz nonlinear systems with time-varying input delay and state quantization constraints. The stabilization is done by an event-triggered delay-independent truncated predictor feedback controller using the information of the upper bound of time-varying input delay (and not its exact value). A sufficient condition on the value of this upper bound in order to guarantee the stability of the closed-loop system under the state quantization constraints is derived. Also, the avoidance of Zeno behavior is proved by finding a lower bound for each two successive events. Various numerical examples illustrate the effectiveness of the obtained results.
Benefiting from the input-to-state stability (ISS) version of the Razumikhin stability theorem, this paper deals with the stabilization of continuous linear input-delay systems with state quantization and without any knowledge about the delay. An event-triggered delay independent truncated predictor feedback (ET-DITPF) controller with a switched feedback control law is proposed to guarantee the globally uniformly asymptotic stability (GUAS)/globally uniformly exponential stability (GUES) of the closed-loop system. As a prominent feature, this controller uses no information about the time delay (neither its value nor its upper bound). In the proposed event-triggered framework, a lower bound for each two consecutive events is derived to show the non-occurrence of the Zeno behavior. Numerical simulations confirm the effectiveness of the obtained theoretical results.
