摘要
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.关键词
