摘要
针对永磁同步风力发电直驱系统应用,采用滑模观测无速度传感器控制算法观测角度和速度的无速度传感器方法,并提出速度采用滑模控制和电流采用非线性PI矢量控制的组合控制策略。仿真实验结果表明:在永磁同步风力发电机可能运行的速度范围内以及加入5%的建模误差时,该组合控制策略工程实现较简单,系统鲁棒性强,动态响应快,从而验证了所提组合控制策略的正确性和可行性。
Aimed at the application of direct-drive permanent magnet synchronous wind power generating system,a combined control tactics that velocity was controlled by sliding mode variable structure vector and current was controlled by nonlinear PI vector controller were submitted based on a sensorless method of velocity using sliding mode observing sensorless control method of velocity to observe angles and velocities.The results show that the proposed combined control tactics are easy to implement,and the combined control system has good robustness and fast dynamic response in the possible running speed scope of motor and adding 5% errors of ideal model for permanent magnet synchronous wind power system,which verifies the accuracy and feasibility of the combined control tactics.
