Event-triggered dissipative control for networked stochastic systems under non-uniform sampling

Abstract

This paper is concerned with dissipative control for networked stochastic systems with an event-triggered transmission mechanism. Different from some existing results, signals from a physical plant are sampled non-uniformly. In order to save precious communication resources, a data-packet processor is introduced to choose necessary data-packets based on a flexible event-triggered condition. By establishing an integral inequality in stochastic setting, which is regarded as a counterpart of Wirtinger-based inequality, a criterion is derived such that the resultant closed-loop system is mean-square stable and dissipative. This criterion is then used to calculate suitable event-triggered controllers in terms of solutions to linear matrix inequalities. An air vehicle system is finally taken to substantiate the validity of the proposed method.
