H ∞ Control for Stochastic Systems with Markovian Switching and Time-Varying Delay via Sliding Mode Design

الملخص EN

This paper addresses the problem of H∞ control for a class of uncertain stochastic systems with Markovian switching and time-varying delays.

The system under consideration is subject to time-varying norm-bounded parameter uncertainties and an unknown nonlinear function in the state.

An integral sliding surface corresponding to every mode is first constructed, and the given sliding mode controller concerning the transition rates of modes can deal with the effect of Markovian switching.

The synthesized sliding mode control law ensures the reachability of the sliding surface for corresponding subsystems and the global stochastic stability of the sliding mode dynamics.

A simulation example is presented to illustrate the proposed method.
