中文摘要：
针对永磁直驱风力发电系统（PMDDWPS）中永磁同步发电机（PMSG）采用PID控制的不足，将2阶非奇异终端滑模变结构控制（SMC）应用于PMSG设计转速外环控制器与电流内环控制器，仿真验证了在2阶非奇异终端SMC下PMSG具有良好的动、稳态性能，对输入机械转矩变化、转速给定变化的响应速度快，对参数摄动具有较强的鲁棒性。构建了永磁直驱风力发电实验平台，实验结果证明了该方法的有效性。
英文摘要：
The traditional design method of permanent magnet synchronous generator（PMSG） in permanent magnet direct drive wind power system （PMDDWPS） is PID control, to overcome the disadvantage of that PID control addresses ,2 order nonsingular terminal sliding mode eontrol（SMC） is employed to design the speed regulator and the current regulator of PMSG.In addition,virtual platform is set up with Matlab/Simulink,simulation results are also given to demonstrate the validity and features of this method.They show that 2 order SMC applications in the PMSG control has good dynamic and steady-state performances, and has fast response to the change of the input mechanical torque, the given speed ,furthermore, it also has good adaptability to the generator parameters＇perturbation.The experiment investigation conducted in the laboratory is made to further verify the effect of the control strategy for PMSG.
