Dynamic event-based output feedback tracking control of nonlinear CPSs with cyber attacks

Abstract

This paper discusses the problem of tracking control for nonlinear CPSs in the presence of resource constraints and multiple cyber-attacks. Firstly, a fuzzy model is built to solve the nonlinear characteristics of CPSs. Secondly, to reduce the burden on communication-resources, two dynamic event-triggered schemes are put forward from plant and reference. Considering the existence of cyber-attacks in dual channel, the deception-attacks model and DoS-attacks model are constructed by stochastic variables. This paper aims to obtain a dynamic event-based tracking controller under cyber-attacks. A sufficient condition of nonlinear CPSs is received to ensure the stochastic stability and desired tracking-performance. Finally, examples are simulated to testify the advantage of the proposed method.
