Fault tolerant H? fuzzy-dynamic output feedback control of nonlinear systems with actuator faults: An LMI approach

This paper addresses the problem of robust fuzzy dynamic output feedback control of a nonlinear discrete time system described by a Takagi -Sugeno fuzzy model. It is assumed that the system is subjected to actuator fault. First, the closed-loop faulty dynamic model of the system and the fuzzy dynamic output feedback controller are introduced. Then, the stability conditions are established via Lyapunov theory, which are formulated in terms of linear matrix inequalities to solve the problem. Finally, a numerical example is presented to illustrate the effectiveness of the proposed controllers.
