Constrained actuator fault tolerant control with the application to a wind turbine

The paper deals with an actuator fault tolerant control (FTC) under constraints for wind turbines. The main issue is to keep a desired value of turbine efficiency coefficient and minimization of tip-speed-ratio. The proposed strategy relies on following stages: a fault is estimated first and then it is compensated with a robust controller. If the compensation is not sufficient, the invariant-set FTC is employed and predictive scheme is utilized. The main goal of predictive approach is to enhance the domain of attraction of a faulty wind turbine. The paper introduces the wind turbine system, benchmark environment and specifies the methodology of solving the formulated FTC problem. The paper presents also application of the considered FTC system to a wind turbine with a special attention on the realization of the following steps of the FTC procedure.
