文档介绍：摘要
一般电动机都是连续旋转,而步进电动却是一步一步转动的,故叫步进电动机。每输入一个冲信号,该电动机就转过一定的角度(有的步进电动机可以直接输出线位移,称为直线电动机)。因此步进电动机是一种把脉冲变为角度位移(或直线位移)的执行元件。随着数字控制系统的发展,步进电动机的应用逐渐扩大。虽然步进电机已被广泛地应用,但步进电机并不能象普通的直流电机、交流电机在常规下使用。它必须由双环形脉冲信号、功率驱动电路等组成控制系统方可使用。
在产品成型之初尚若利用仿真软件设计电路,仿真是对其进行研究的一个重
要的不可缺少的手段,在仿真环境中进行控制程序的调试,这不仅不需要实际的硬件设备,更能部分满足工程需求。MATLAB 语言是一种面向科学工程计算的高级语言,它集科学计算、自动控制、信号处理、神经网络、图像处理等功能于一体,是一种高级的数学分析与运算软件,可用作动态系统的建模和仿真。基于MATLAB的仿真环境下建立了步进电机模型,不仅仿真结果与实物仿真一致,而且其仿真方法简单,仿真时间大大缩短,是一种理想的步进电机仿真研究方法。

ABSTRACT
General Motors is a continuous rotation, while the step is electric rotating step by step, so called stepper motors. Each input of a red signal, the motor will turn a certain angle (some stepper motors can be directly output line displacement, known as the linear motor). Therefore, the stepper motor is a pulse into the point of displacement (or linear displacement) of the implementation of ponents. With the development of digital control systems, stepper motor application gradually expanding. Although the stepper motor has been widely used, but the stepper motor does not like a normal DC motor, AC motor used in the routine. It must be double-ring pulse signal drive posed of control before use.
