Robust H∞ control on nonlinear uncertainty stochastic time-delay systems with switched controller

In this paper, nonlinear uncertainties time delay stochastic systems with hybrid states are discussed. Based on Lyapunov functional and Razumikhin techniques, sufficient condition is established for robust H
_∞
control of the system. For a class of hybrid systems that are probed in this paper, exponential stability criteria obtained based on the Gronwall-Bellman inequality, switching law is designed for robust H
_∞
control of the system.
