摘要
Abstract
Considering the nonlinearity,uncertainty and strong interference existing in a direct drive permanent magnet synchronous wind power generation system,a maximum power point tracking strategy is proposed based on the sliding-mode adaptive control algorithm. To real-time estimate the generator’s electromotive force,as well as the system speed and torque,a sliding-mode controller and an adaptive observer are designed by combining the sliding-mode control and adaptive control algorithm,respectively. In addition,the control performances of the sliding-mode adaptive controller under three kinds of wind speeds(i.e.,gradient wind,gust,and random wind)are studied. Finally,simulations and verifications are conducted based on Matlab-Simulink,and results indicates that the accurate estimation of the genera?tor rotor’s angular position and the real-time estimation of the system speed and torque can be realized.关键词
