Abstract:In order to make maximal use of wind power and improve the efficiency of wind power generation system, a maximum power point tracking method based on sliding mode control was proposed. The control system of wind turbine was established, and the sliding plane was established based on the sliding mode control principle. In addition, the sliding mode control rate was designed, and the stability was analyzed. The simulation studies for the control system were carried out with the Matlab/Simulink. The simulated results show that the actual electromagnetic torque can quickly track the desired electromagnetic torque value, and the correctness and validity of the proposed control strategy are verified. The sliding mode control is independent on the wind speed, has good robustness and high control precision, and can achieve the maximum wind power point tracking.
Keywords:wind turbine  maximum power point tracking  sliding mode control  stability  control system  output power  electromagnetism torch
