An active fault-tolerant control schema for delayed systems
Résumé
Nowadays fault-tolerant control (FTC) strategies become unavoidable to ensureat the same time control and fault diagnosis objectives. Furthermore, delayed system are increasingly encountered in many real-world applications. Therefore, an active fault-tolerant control strategy for delayed system is presented in this paper. The core of the proposed strategy is the simultaneous state and fault estimations provided by an observer known as multi-integral observer. Sufficient conditions for ensuring the control law stability as well as the estimation error convergence of the observer are given employing the LMI framework. The effectiveness of the proposed approach is illustrated via a simulation example.
