The main goal of this paper is to develop a fault tolerant control system that incorporates both reliability and dynamic performance of the system for control reconfiguration. Once a fault has been detected and isolated, the reconfiguration strategy proposed in this paper tries to find possible structures of the faulty system that preserve pre-specified performance, calculate the system reliability, compute new controller gains and finally search the optimal structure that has the “best” control performance with the highest reliability. The proposed approach is illustrated through a simulation example.
