The Application Of Model Free Adaptive Control In The Control System Of Large-Scale Wind Turbine

The main task of the paper is control a Major Variable Pitch Wind Turbine Generator with model free adaptive controller so as to make it run well. First, the paper presents the survey of Generator. Second, the paper introduces the modeling of the Major Variable Pitch Wind Turbine Generator in detail and presents the simulink result of the Major Variable Pitch Wind Turbine Generator without controller. Third, in the third chapter the paper puts forward a control tactics of the Major Variable Pitch Wind Turbine Generator . For comparing conveniently with the model free adaptive controller that have been designed in the later chapters, this paper gives the simulink result of the Major Variable Pitch Wind Turbine Generator with PID controller in brief. Finally, this paper designs the model free adaptive controller, and gives satisfying results.This paper has simulated the controller with MATLAB. From the point of tracking performance and anti-disturbance, the control effect of model free adaptive controller is better than PID controller. That is to say, the model free adaptive controller can depress the oscillation more efficiently and has a rapid rising response, arrive at stabilization more rapidly.In the end, this paper makes a summary for the whole. It induces the solved problem and the got conclusion, and shows the future development of the model free adaptive control theory.
