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.

具有时间延迟的离散时间切换系统的鲁棒容错控制

这项研究概述了延迟的离散时间切换系统的主动容错控制问题。使用切换比例积分观测器和多个Lyapunov-Krasovski函数，建立了不太保守的充分条件，以通过线性矩阵不等式形式设计鲁棒的故障估计（FE）算法。然后，基于此快速而精确的有限元信息，可实现容错性能，以补偿执行器故障的影响，同时使闭环系统稳定。通过仿真实例和比较结果证明了所提策略的有效性。
