The exploitation of wind power will improve the energy structure and ease the power shortage, which is an effective approach to solving the world energy crisis. But the wind power generation system was a typical nonlinear system, which was hard to be controlled exactly by traditional controllers and the sliding mode control was proposed, the mathematical models of wind energy conversion system was created, which was combined with mechanical automation and electrical, the sliding mode control strategy was presented, the sliding surface was designed with equivalent controller and switching controller. The model and control strategy was established with MATLAB and the simulation result shows this control system with speed tracking performance, which can effectively implement maximum energy capture.
