摘  要

 本文介紹直流電機(jī)控制的MATLAB仿真，主要以PC機(jī)為平臺，采用matlab/simulink作為仿真工具，實(shí)現(xiàn)直流電機(jī)控制的變化顯示。我們用 Madab對各環(huán)節(jié)先進(jìn)行虛擬設(shè)計仿真，在反復(fù)修改，觀察各環(huán)節(jié)輸出波形符合要求后，再選用器件安裝調(diào)試起到較好的效果。
 本文首先論述了直流電機(jī)控制的MATLAB仿真的作用和其優(yōu)勢，然后討論通過系統(tǒng)的軟件設(shè)計，實(shí)現(xiàn)了對直流電機(jī)采用matlab/simulink作為仿真工具建立直流電機(jī)的數(shù)學(xué)模型，利用Matlab軟件中的動態(tài)仿真工具Simulink，通過實(shí)例進(jìn)行實(shí)時仿真。實(shí)現(xiàn)人為機(jī)械特性，其次是進(jìn)行對直流電機(jī)開環(huán)調(diào)速系統(tǒng)的仿真和轉(zhuǎn)速閉環(huán)控制的直流調(diào)速系統(tǒng)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.
