步进电动机加速运行控制研究

Studying on Control of Step Motor Accelerative Running

步进电机在起动、变速或停止时,会出现起动时间慢、起动失步甚至是不能起动、以及停止冲击大等现象。因此对步进电机起动加速运行和停止减速运行进行控制,对于实际的控制系统具有积极的意义。在建立步进电机数学模型和传递函数的基础上,分别采用简单加速算法和指数加速算法对电机加速度运行进行控制;通过仿真和实验,结果表明比起简单加速算法,指数加速算法能够更好地控制步进电机加速运行。

According to establishing the stepping motor of mathematical model and transfer function, This paper introduces the exponent accelerating-algorithm and the simple accelerating-algorithm which carry on controlling the stepping motor respectively. The exponent accelerating-algorithm has gone through simulation and experiment. It proves that exponent accelerating-algorithm can control the stepping motor accelerative running better than the simple accelerating-algorithm.
