Static Output Feedback Control for Fuzzy Systems With Stochastic Fading Channel and Actuator Faults

Abstract

This work focuses on the issue of static output feedback control for Takagi-Sugeno (T-S) fuzzy systems in the discrete-time domain. Both the fading channel and actuator faults are determined by a set of stochastic variables. Specifically, an actuator fault is described by a nonhomogeneous Markov chain, and fading channels are characterized by the l-order Rician fading model. Using the Lyapunov-Krasovskii function, sufficient conditions are established, and controller gains are developed. Finally, the practical mass-spring-damping model is expressed to verify the practicability of the theoretical results.
