Robust H_∞ Fault-Tolerant For A Class Of Networked Control System Based On Static Output Feedback

摘要

This paper focuses on the networked control system (NCS) with sensor and actuator failures, considering the impact of the network delay and parameter uncertainty on system performance, We propose a design of robust H_∞ fault-tolerant control based on static output feedback. The closed- loop networked control system possessing asymptotically stable is given by static output feedback, fault-tolerant control theory and Lyapunov stability theory. Then the H_∞ fault-tolerant controller is deduced by using linear matrix inequalities. Numerical simulation illustrates the method has a good robust fault tolerant capability that the conclusions are valid.
