中文说明：
相比于传统使用的电机，永磁同步电动机（PMSM）具有着比较高的工作效率、比较高的力矩惯量比、比较高的能量密度和环保节能等优越特性，所以对永磁同步电机进行控制调速方面的研究有着相当重要的意义。我们设定电机转速初始值作为给定值，然后与反馈的实际值进行比较，得到的差值输入PI控制器进行控制，得到交轴电流。同时三相绕组输出的电流经过clarke变换和park变化得到电流的实际值，分别与给定值进行比较，将比较后的值再进行park转换，得到的结果经过SVPWM技术调制之后输入到逆变器，继而可以驱动三相电机。
English Description：
Compared with the traditional motor, permanent magnet synchronous motor (PMSM) has higher work efficiency, higher moment inertia ratio, higher energy density, environmental protection and energy saving, so it is of great significance to study the control and speed regulation of PMSM. We set the initial value of the motor speed as the given value, and then compare with the actual value of the feedback, the difference is input into the PI controller for control, and the quadrature axis current is obtained. At the same time, the output current of the three-phase winding is transformed by Clarke transform and park change to get the actual value of the current, which is compared with the given value respectively. The compared value is converted by park, and the result is input to the inverter after SVPWM technology modulation, and then the three-phase motor can be driven
