A resonant sliding mode control strategy based on the resonant sliding film surface is proposed to control the turbine-side converter of the wind turbine so that the wind turbine can be connected to the grid smoothly under the condition of unbalanced grid voltage. Taking the doubly-fed asynchronous wind generator working under unbalanced grid voltage as the control object, establish its mathematical model and its generator-side converter. Taking the instantaneous power in the α β static coordinate system as the state variable of the sliding mode controller, the resonant sliding mode controller is studied, its parameters are designed, and experiments are carried out in the simulation platform MATLAB. A 1.5MW motor model was established and tested, and it was verified that the resonant sliding mode control strategy can control the grid voltage without static error and realize the smooth grid connection of wind turbines.
