The pitch angle control of squirrel-cage induction generator wind power generation system using sliding mode control

The pitch angle controller is designed for SCIG wind power system by using sliding mode control to level the output power of wind turbine generation (WTG) at the rated power. The WTG system model is established by using small signal method. Then the pitch angle control system is designed based on the sliding mode control via reaching law. At last, the simulations are given by matlab software comparing with other two PID control method, the simulation results show that the proposed controller has more robustness and little deviation.
