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。(Used compared to traditional motor, permanent magnet synchronous motor (all-digital fuzzy) has a higher efficiency, higher moment of inertia ratio, higher energy density and superior properties such as environmental protection and energy saving, so the control of permanent magnet synchronous motor speed regulation research has important significance. We set the initial value of motor speed as the given value, and then compare it with the actual value of feedback. The difference obtained is input to PI controller for control, and the current of crossaxis is obtained. At the same time the output three-phase winding current through Clarke transformation and park changes the current actual value, compared with a given value respectively, after comparing the value of the park transformation again, the result after SVPWM modulation technology input to the inverter, which in turn can drive three-phase motor.)

编制MCS-51程序使步进电机按照规定的转速和方向进行旋转，并将已转动的步数显示在数码管上。 　　步进电机的转速分为两档，当按下S1开关时，加速旋转，速度从10转/分加速到60转/分。当松开开关时，减速旋转，速度恢复为10转/分。当按下S2开关时，按照逆时针旋转；当松开时，按照顺时针旋转。 　　本程序要求使用定时器中断来实现，不准使用程序延时的方式。(The MCS-51 program is programmed to rotate the stepper motor according to the specified speed and direction, and the number of steps that have been rotated is displayed on the digital tube. Stepper motor speed is divided into two gears. When the S1 switch is pressed, the speed is accelerated from 10 rpm to 60 rpm. When the switch is loosened, the speed will be reduced to 10 rpm. When pressing the S2 switch, rotate counterclockwise; when loosening, rotate clockwise. This procedure requires the use of timer interrupt to achieve, do not use the way of program delay.)
