The vertical axis wind turbine and Switched Reluctance Generator （SRG） are regarded as objects. Based on the tracking of wind speed, vertical axis switch reluctance wind power system MPPT dynamic Sliding Mode Control （SMC） algorithm is studied, the principle of SMC is introduced, and the sliding mode controller is designed. Matlab/simulink is used to establish the system simulation model, step changes of wind speed in different condition are simulated. The simulation results show that the design of SRG wind power synovial controller has good robustness, and can make the switch reluctance wind power generation system have good dynamic performance to achieve maximum power point tracking and to provide theoretical support for the practical application.
