摘要

针对一类具有状态时滞的不确定线性系统, 详细阐述了该系统基于状态观测器的H鲁棒容错控制问题. 当系统状态不可测时, 构造状态观测器, 并考虑状态观测器反馈回路传感器失效, 引入观测误差, 通过构造闭环增广系统的Lyapunov泛函, 设计出了有容错性能的状态观测器和基于该观测器 的状态反馈控制器, 使得闭环增广系统渐近稳定, 并满足H性能指标. 通过求解一个线性矩阵不等式就可同时得到观测器增益和控制器增益矩阵. 最后给出仿真算例, 验证了此方法的有效性.

Abstract

This paper describes in detail the H robust fault-tolerant control problem for a type of linear uncertain systems with state-delay based on state-observer. When states of the system are unmeasurable, a state-observer is constructed and the observation error is considered taking sensor failures in the state-observer feedback loop into account. Using the Lyapunov function method, the state-observer with fault-tolerant performance against sensor failures in observer feedback loop and the state feedback controller based on state-observer are designed such that the closed-loop system augmented with observation error is asymptotically stable and satisfy the H performance index. By solving a linear matrix inequality the observer and controller gain matrices can be obtained simultaneously. Finally, a simulation example shows the effectiveness of the proposed method.
