Integrated Fault Tolerant Control for Closed-Loop System with Uncertain Packet Loss

Abstract

In this paper, an integrated fault tolerant control scheme is developed for closed loop systems with unknown packet loss rate. Firstly, the closed loop system with packet loss is modeled as a switched system with uncertain system parameters, then the fault diagnosis observer and fault tolerant controller are constructed, and the integrated design issue is transformed into a multi-objective solution problem of the extended system under weighted performance. Furthermore, the parameters of the fault observer and the fault tolerant controller are solved by approaches including average dwell time, multi-Lyapunov functions and relaxation matrix. Finally, simulation results show the effectiveness and superiority of the proposed method.
