Robust fault‐tolerant control for discrete‐time switched systems with time delays
Kenza Telbissi, Abdellah Benzaouia
Abstract
Summary This study outlines the problem of active fault‐tolerant control for delayed discrete‐time switched systems. Using switched proportional‐integral observer and multiple Lyapunov‐Krasovski function, less conservative sufficient conditions are established to design a robust fault estimation (FE) algorithm via linear matrix inequality form. Afterward, a fault‐tolerant performance is realized based on this fast and exact FE information to compensate the effect of actuator fault while stabilizing the closed‐loop system. The efficiency of the proposed strategy is proved through simulation examples and comparison results.
