Abstract: | 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. |
