Adaptive Switching Control of Wind Power System with Actuator Failures and Uncertainties

For the wind power generation system with actuator failures and uncertainty, the switching control method is used to study it. First of all, the working modes and states of this system are discussed. The failure and recovery of the actuators are regarded as two events, and the wind power system can be regarded as the wind power system with two event switching modes, including temporary failure event mode and health recovery event mode; Secondly, the switching control method is adopted, that is, the controller is stopped during the actuator failures, and the controller is applied after the actuators recover well. Then, based on Lyapunov stability theory, the switching controller of the wind power system with actuator failures is given. Finally, the double-fed wind power system is studied to prove the effectiveness of the proposed control method.
