Sliding Mode Control Under Deception Attacks

Abstract

In this chapter, the issue of observer-based sliding mode control is addressed for fuzzy stochastic semi-Markovian switching systems (S-MSSs) under cyber attacks. The underlying control signal is vulnerable to the deception attacks, in which the opponents inject fake data into the signal in a probabilistic way. Inspired by the unmeasurable states, an integral sliding surface dependent on a fuzzy observer is designed. Then, in consideration of the deception attacks, the conditions are established to achieve the stochastic stability for fuzzy sliding mode dynamics. Moreover, the proposed observer-based sliding mode control law guarantees the reachability of the sliding region. In the end, a single-link robot arm model is given to demonstrate the availability of the given results.
