Event-Triggered Faults Tolerant Control for Stochastic Systems with Time Delays

Abstract EN

This paper is concerned with the state-feedback controller design for stochastic networked control systems (NCSs) with random actuator failures and transmission delays.

Firstly, an event-triggered scheme is introduced to optimize the performance of the stochastic NCSs.

Secondly, stochastic NCSs under event-triggered scheme are modeled as stochastic time-delay systems.

Thirdly, some less conservative delay-dependent stability criteria in terms of linear matrix inequalities for the codesign of both the controller gain and the trigger parameters are obtained by using delay-decomposition technique and convex combination approach.

Finally, a numerical example is provided to show the less sampled data transmission and less conservatism of the proposed theory.
