Abstract: In order to ensure the stable operation of direct-driven permanent magnet wind turbines under complex wind conditions, P ut forward a kind of self immunity ADRC control and fractional order calculus P ID the combined control strategy. A continuous and smooth tal function based on fal function is designed to solve the problem of the origin flutter of the system, and the ADRC controller was redesigned. In current control, fractional calculus PID control was used instead of integer calculus P ID controller to ensure the reliable operation of wind turbine. The simulation results show that the proposed control strategy is superior to the traditional ADRC and the improved ADRC in terms of static stability and dynamic response speed.
