摘要
    隨著計(jì)算機(jī)技術(shù)和信息技術(shù)等高新技術(shù)的快速發(fā)展,仿真技術(shù)也得到迅速的推動(dòng)。MATLAB是當(dāng)前控制領(lǐng)域最常用的仿真軟件，通過(guò)MATLAB自動(dòng)控制實(shí)驗(yàn)工具箱，可以很方便實(shí)現(xiàn)對(duì)系統(tǒng)的仿真設(shè)計(jì)。本文主要介紹了MATLAB仿真技術(shù)及自動(dòng)控制原理的概念、特點(diǎn)以及發(fā)展情況。還以MATLAB為基礎(chǔ)平臺(tái)，用實(shí)例詳細(xì)介紹了MATLAB軟件在自動(dòng)控制原理實(shí)驗(yàn)教學(xué)中的應(yīng)用，分析了MATLAB的功能及如何在MATLAB語(yǔ)言提供的仿真環(huán)境SIMULINK下實(shí)行自動(dòng)控制原理的仿真。具體的實(shí)驗(yàn)包括：基于MATLAB的二階系統(tǒng)階躍響應(yīng)、控制系統(tǒng)的穩(wěn)定性分析、系統(tǒng)頻率特性測(cè)量、連續(xù)系統(tǒng)串聯(lián)校正（超前校正、滯后校正、滯后—超前校正）、基于MATLAB頻域分析和磁盤驅(qū)動(dòng)控制系統(tǒng)綜合設(shè)計(jì)。通過(guò)從以上方面的論述，得出結(jié)論：利用MATLAB對(duì)自動(dòng)控制原理實(shí)驗(yàn)進(jìn)行仿真與分析，是研究自動(dòng)控制原理的重要手段；MATLAB軟件不但使實(shí)驗(yàn)方法得到改進(jìn)，而且提高了實(shí)驗(yàn)效率和實(shí)驗(yàn)水平。

Abstract
    With the rapid development of high technology like computer technology and information technology, the simulation technology is also promoted rapidly. Currently, MATLAB is the most common simulation software used in control field. The simulation and design of the control systems can conveniently be achieved using the MATLAB control system toolbox.
 This thesis describes MATLAB simulation technology and the concept, characteristics and development of theory of automatic control. Furthermore, the application of MATLAB software in the experiments teaching of theory of automatic control is introduced basing on the examples. The function of MATLAB and how to simulate the experiments of theory of automatic control in SIMULINK are analyzed. The experiments include: MATLAB-based unit step response of second order system, the stability analysis for control system, measurement of system frequency characteristics, cascade compensation of continuous system (lead compensation, lag compensation, lag and lead compensation), MATLAB-based frequency domain analysis, general design of disk drive control system.
 In conclusion, simulating and analyzing the experiments of the theory of automatic control using MATLAB is the important research method of the theory automatic control. Not only the experimental methods are modified, but also the experiment efficiency and the experiment level are improved.
