This study investigates the state and fault estimation, and fault-tolerant of discrete linear parameter varying (LPV) systems with integral measurements based on event-triggered mechanism (ETM). First, for LPV systems with integral measurements, a codesign scheme of a fault observer and a fault-tolerant controller based on ETM is proposed. Then, a sufficient condition for the proposed scheme is then specified and proved to meet the $H_{\infty }$ performance index. Upon, the gain matrices of the observer and fault-tolerant controller are obtained using linear matrix inequality (LMI). Finally, the feasibility and effectiveness of the proposed method are validated by a numerical example.

本研究通过基于事件触发机制 (ETM) 的积分测量研究了状态和故障估计以及离散线性参数变化 (LPV) 系统的容错性。首先，针对积分测量的LPV系统，提出了一种基于ETM的故障观测器和容错控制器的协同设计方案。然后，然后指定所提出方案的充分条件并证明满足$H_{\infty }$性能指标。然后，使用线性矩阵不等式 (LMI) 获得观测器和容错控制器的增益矩阵。最后通过数值算例验证了所提方法的可行性和有效性。
