永磁同步电机(PMSM)电流转速双闭环PI控制，采用矢量控制（FOC）中的id 0方式，以空间矢量脉宽调制来实现磁链圆跟踪。对负载转矩进行交轴电流前馈以抑制外负载扰动。-Permanent Magnet Synchronous Motor (PMSM) current double closed loop speed PI control, vector control (FOC) of id 0 mode, space vector pulse width modulation to ac

实现永磁同步电机的无位置控制，采用滑模算法计算转子位置角度，精度高，相应速度快。(Realize position control of permanent magnet synchronous motor, rotor position Angle is obtained by using the sliding mode algorithm, high accuracy, the corresponding speed.)
