摘要
步进电机是一种能够精确定位的执行元件,但由于自身的特性,容易出现堵转、丢步的现象,因此对步进电机系统的定位准确度进行控制,对实际控制系统有着重要作用。该文基于二相混合式步进电机的数学模型,运用专家PID控制算法对步进电机的转速进行控制。通过Matlab仿真和实验结果表明,专家PID控制对步进电机速度控制效果较好,为步进电机的应用提供了一种可选的控制方法。
Stepping motor was a kind of device which can precisely locate the stepping motor system. But because of their own characteristics,the phenomenon of blocking and losing was easy to appear,so it was important to control the positioning accuracy of the stepper motor system. This paper was based on the mathematical model of two-phase hybrid stepper motor,the speed control of the step motor was controlled by the expert PID control algorithm. The results show that the control effect of the expert PID control is better,an optional control method is provided for the application of the stepping motor.
