摘  要

 本文介绍直流电机控制的MATLAB仿真，主要以PC机为平台，采用matlab/simulink作为仿真工具，实现直流电机控制的变化显示。我们用 Madab对各环节先进行虚拟设计仿真，在反复修改，观察各环节输出波形符合要求后，再选用器件安装调试起到较好的效果。
 本文首先论述了直流电机控制的MATLAB仿真的作用和其优势，然后讨论通过系统的软件设计，实现了对直流电机采用matlab/simulink作为仿真工具建立直流电机的数学模型，利用Matlab软件中的动态仿真工具Simulink，通过实例进行实时仿真。实现人为机械特性，其次是进行对直流电机开环调速系统的仿真和转速闭环控制的直流调速系统仿真。

Abstract

 This article introduces the DC motor control MATLAB simulation, mainly to a PC as a platform, using matlab / simulink as a simulation tool, DC motor control to achieve the changes show. we used Madab on the first part of a virtual simulation design, in repeated Laws, observation of all sectors to meet the requirements after the output waveform, selection of the device installed to debug a good result.
This paper discusses DC motor control MATLAB simulation of the role and its strengths, then discussed and adopted the system software design,
implementation of the DC motor using matlab / simulink as a simulation tool for the establishment of a mathematical model DC, Matlab software used in dynamic simulation tool Simulink, through examples of real-time simulation. Implementation of man-made machinery, this was followed by a DC motor on the open-loop speed control system simulation and speed closed-loop control of the DC converter system simulation.

Keywords:  matlab；DC Motor；Simulation
