A novel active fault tolerant control design with respect to actuators reliability

In this paper, actuators reliability analysis is considered in the design of active fault tolerant control system. The main objective consists on the synthesis of a fault tolerant controller gain which guarantees a highest overall system reliability. Benefit of incorporating reliability indicators on the controller gain design is to manage effectively the control inputs in order to increase the remaining life time of a system in the presence of faults. A reliability analysis of system modeled by a state space representation is proposed. A controller gain design is reformulated as an Linear Matrix Inequality (LMI) problem and synthesized through an effective admissible model matching approach.
