Time-trajectory based active fault-tolerant control

In this note, we present a model-free approach to solve an active fault-tolerant control problem in the behavioral framework. In our control structure, we do not require an explicit fault diagnosis module that identifies the complete fault information. Instead, a new controller is designed based only on the measurements generated by the system in real-time. The interconnection between two dynamical systems plays a significant role within this approach. In our setting, we consider any occurring fault is the cause of undesired dynamics occurring in the closed-loop. To compensate these dynamics, the controller is reconfigured on-line without using a model of the plant.
