| 摘 要： | 针对无刷双馈风力发电机直接转矩控制转矩脉动较大的问题,提出一种对控制绕组磁链旋转角进行模糊控制与空间矢量调制(SVPWM)技术相结合的控制方法,调制合成合适的控制电压,对常规直接转矩控制进行改进,使直接转矩控制中的脉动转矩明显减小.该控制方法易于实现,仿真结果表明系统转矩脉动大大减小,控制性能得到了改善.

| Abstract: | In order to reduce the large torque ripple which exists in the conventional brushless doubly-fed wind generator direct torque control,a novel method based on fuzzy control and space vector modulation to control winding flux linkage rotation angle was proposed.The reasonable control voltage is composed,and the general DTC is improved to decrease the impulse torque obviously.The method is simple and easy to be implemented.Simulation result shows that the torque ripple is decreased drastically and the performa... |
