On active fault-tolerant control in behavioral context
Résumé
In this note, we present a model-free approach to solve an active fault-tolerant control problem for linear time-invariant systems using the mathematical framework of behavioral theory. In our control structure, we do not require an explicit fault diagnosis module to identify the complete fault information. Instead, a new controller is designed based only on the knowledge of the desired behavior, and the measurements collected in real-time. The interconnection between two dynamical systems plays a significant role within this framework. In our setting, we consider any occurring fault is the cause of an undesired behavior. To compensate the effects of faults, we present a way that reconfigures the controller directly, without using a model-based fault diagnosis unit such that the interconnected system achieves the desired specifications at anytime.
