matlab步进电机转速控制仿真(课程设计)

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。数字控制系统的发展，步进电动机的应用逐渐扩大。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 the components. 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 circuit composed of control before use. Used in the product forming the beginning of Shang Ruoli simulation software circuit simulation is an important study of its Indispensable want of means to control program simulation environment for debugging, not only without actually hardware, better Bufen meet the engineering requirements. Matlab language is a science and engineering calculations for high-level language, which combines scientific computing, automatic control, signal processing, neural networks, image processing and other functions into one, is an advanced mathematical analysis and computation software can be used as dynamic Modeling and Simulation. MATLAB-Simulink simulation environment based on the establishment of a stepping motor under the model, simulation results not only consistent with the physical simulation, and the simulation method is simple, the simulation time is shortened, it is an ideal stepping motor simulation methods.
