【正文】 基于 SIMULINK 的永磁同步電機(jī)控制系統(tǒng)的仿真設(shè)計(jì)中文摘要在 MATLAB/SIMULINK 中建立獨(dú)立的功能模塊主要有：PMSM 本體模塊、矢量控制模塊、電流滯環(huán)控制模塊、速度控制模塊等。同時(shí)進(jìn)行功能模塊的有機(jī)整合，搭建 PMSM 控制系統(tǒng)的仿真模型采用雙臂環(huán)控制，速度環(huán)采用 PI 控制，電流環(huán)采用滯環(huán)電流控制。仿真結(jié)果證明了該方法的有效性，同時(shí)該模型也適用于驗(yàn)證其他控制算法的合理性，為實(shí)際電機(jī)控制系統(tǒng)的設(shè)計(jì)和調(diào)試提供的新的思路。為了實(shí)現(xiàn)高性能的電流環(huán)控制，對(duì)比了常規(guī)電流滯環(huán)控制和三角波載波比較方式的電流滯環(huán)控制。在 MATLAB 中搭建了兩種電流滯環(huán)控制方式的仿真模型，通過仿真得出采用常規(guī)電流滯環(huán)控制對(duì)系統(tǒng)的整體性能影響比較大，而采用三角載波比較方式的電流滯環(huán)控制容易獲得良好的控制效果。采用三角載波比較方式的電流滯環(huán)控制的仿真結(jié)果進(jìn)一步驗(yàn)證了本文分析的正確性，并且為系統(tǒng)的整體設(shè)計(jì)提供了理論基礎(chǔ)。關(guān)鍵詞：永磁同步電動(dòng)機(jī)；SIMULINK；電氣系統(tǒng)模型庫(kù) Simulation of control system for the Permanent Magent SynchronousAbstractThe paper as the example of the control system of permanent synchronous motor, mainly introduces how to get the simulation of AC driven system under the environment of SIMULINK by using the toolbox of power system, then discusses the effect of adjuster PI on the revolution during suddenly changed load.In MATLAB/SIMULINK it establishes the independent function modules。 PMSM body module, vector control module, the current hysteresis control, speed control module, function module and so on. At the same time, it integrates the function module and establishes the simulation module of PMSM control system. this system adopts double closedloop control system, the PI control the speed loop, the sluggish loop electric current controls electric current loop the simulation result proves the effective method of the indeperdent function modules. This model also applies to test and verify the reasonableness of thought for both design of practical electrical engineering control system and debugging.For the sake of highperformance currentloop in position servo system, we studied general hysteresisband currentcontrol and triangular carrier wave hysteresisband currentcontrol. Simulation models of the two mode were build in MATLAB, by the simulation analysis, we can know that general hysteresisband currentcontrol will seriously influence on performance of system, and triangular carrier wave hysteresisband currentcontrol can be used for good control performance. When triangular carrier wave hysteresisband currentcontrol was used, analytical results are good agreement with the feasible simulation results, and the results can provide theoretical basis for the design of servo system.Key words: permanent mag synchronous motor。 SIMULINK。 toolbox of power system.目 錄第一章 前 言 .............................................................................................................................1 課題研究背景 .........................................................................................................................1 永磁同步電機(jī)發(fā)展?fàn)顩r .............................................................................................1 永磁同步電機(jī)控制系統(tǒng)的發(fā)展 ..............................................................................1 計(jì)算機(jī)仿真技術(shù)的發(fā)展 .............................................................................................3 MATLAB 簡(jiǎn)介 .....................................................................................................................3 MATLAB 軟件的簡(jiǎn)介 .............................................................................................3 MATLAB 仿真工具箱簡(jiǎn)介 ...................................................................................8 本文主要任務(wù) .........................................................................................................................9第二章 永磁同步電機(jī)的結(jié)構(gòu)及其數(shù)學(xué)模型 ........................................................................9 永磁同步電機(jī)的概述 .........................................................................................................9 同步電機(jī)的基本工作原理 ........................................................................................9 永磁同步電機(jī)的基本結(jié)構(gòu)及其分類 .....................................................................9 永磁同步電機(jī)的特點(diǎn)與應(yīng)用 .................................................................................11 永磁同步電機(jī)的數(shù)學(xué)模型 ...............................................................................................13 電壓平衡方程 ..............................................................................................................14 磁鏈方程及感應(yīng)電動(dòng)勢(shì)方程 ...............................................................................15 永磁同步電機(jī)在各個(gè)坐標(biāo)系下的數(shù)學(xué)模型 ..............................................................17 磁同步電機(jī) ABC 坐標(biāo)下數(shù)學(xué)模型 ...............................................................17 磁同步電機(jī) ??坐標(biāo)系下數(shù)學(xué)模型 ..............................................................18 永磁同步電機(jī) dq 坐標(biāo)系下數(shù)學(xué)模型 ...............................................................18第三章 永磁同步電機(jī)控制系統(tǒng)工作原理 ..............................................................................19 PWM（PULSEWIDTH MODULATION）技術(shù) ..................................................19 PMSM 控制系統(tǒng)的組成 ....................................................................................................22 PMSM 控制系統(tǒng)的運(yùn)行原理 ..........................................................................................23第四章 永磁同步電機(jī)控制系統(tǒng)仿真設(shè)計(jì) ...........................................................................24 DQ 坐標(biāo)系與 ABC 三相坐標(biāo)系轉(zhuǎn)換 .........................................................................24 PI 調(diào)節(jié)器 ................................................................................................................................27 利用 SIMULINK 構(gòu)建 PMSM 控制系統(tǒng)仿真模型 ................................................30 仿真結(jié)果 .................................................................................................................................31全文總結(jié) ..............................................................................................................................................35致 謝 ..............................................................................................................................................36參考文獻(xiàn) ..........................................................................................
