中文摘要:针对一类约束多传感器线性故障系统，提出了一种基于鲁棒预测控制策略的容错控制方案.首先为多传感器线性系统设计了观测器，然后离线设计不变集列，使得时变的状态估计误差存在于相应的不变集列中，利用不变集的理论提出了一种新的故障检测的方法，最后基于鲁棒预测控制策略为故障系统设计了容错控制器，给出了闭环系统鲁棒稳定性的证明.仿真结果证明了方法的可行性。

RMPC Fault Tolerant Control of Constrained Multi-sensor Linear Systems

Abstract:In this paper, for a class of constrained multi-sensor linear fault system, we propose a fault-tolerant control scheme based on robust predictive control strategy.Firstly, the observer is designed for multi-sensor linear systems，then, invariant set sequences is designed off-line, and the time-varying state estimation error exists in the corresponding invariant set sequences. A new fault detection method is proposed based on the invariant set theory. Lastly, we design fault-tolerant controller for fault system based on robust predictive control strategy, and the closed-loop system robust stability is proved. The simulation results show that the method is feasible.
