摘要
Abstract
In this paper,the maximum power tracking control method for a direct drive permanent magnet synchronous wind power generation system operating below the rated wind speed is studied,and an improved disturbance observer control(DOBC)strategy is proposed. In consideration of the disturbance caused by real-time torque and speed estima?tion error of the wind power generation system load,a load-torque disturbance observer(LDOB)is designed based on speed estimation,and it is further applied to the control of disturbance observer at three wind speeds,including gust, gradient wind,and random wind. In this way,the estimation of system torque is compensated to improve the observa?tion accuracy of the disturbance observer under load torque mutation. Finally,the composite controller is simulated and analyzed using Matlab-Simulink,and results verify the effectiveness of the proposed composite controller.关键词
