中文说明：
PMSG网侧的结构包括逆变器、PWM发生器、电压矢量控制。采用电压外环和电流内环的双闭环控制。设计电流控制器时，希望稳态电流无静差，而且动态要求上，永磁直驱风力发电系统中不允许在电流调节过程中有太大的电流超调。
English Description：
The structure of PMSG network side includes inverter, PWM generator and voltage vector control. The double closed-loop control of voltage outer loop and current inner loop is adopted. When designing the current controller, it is expected that the steady-state current has no static error, and in terms of dynamic requirements, too much current overshoot is not allowed in the process of current regulation in the permanent magnet direct drive wind power generation system
