摘 要 开关磁阻电动机(Switched Reluctance Motor，简称SRM)调速系统(Switched Reluctance Motor Drive，简称SRD)是一种新型的调速系统。因其结构简单，鲁棒性好，启动转矩大及调速范围宽等特点，日益受到国内外学者的关注.本文着重描述了开关磁阻电动机的非线性数学模型，并通过MATLAB仿真对调速系统进行了仿真，结果表明数学模型与仿真结果基本吻合。 关键词：开关磁阻电动机；调速系统；数学模型；MATLAB仿真 ABSTRACT Switched Reluctance Motor Drive is a new adjustable-speed motor system. Its structure is simple,SRD has robust very well.Its starting torque and a wide range of characteristics of speed, increasing the concern of scholars at home and abroad. This article focuses on the SRM nonlinear mathematical model, and the speed regulation system was studied through MATLAB,The results show that mathematical models and simulation basically consistent with the results. Key words: switched reluctance motor drive；Speed Control System mathematic model；MATLAB simulation 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc200168509 摘 要 PAGEREF _Toc200168509 \h I HYPERLINK \l _Toc200168510 ABSTRACT PAGEREF _Toc200168510 \h II HYPERLINK \l _Toc200168511 1.1开关磁阻电机调速系统的历史及发展现状 PAGEREF _Toc200168511 \h 1 HYPERLINK \l _Toc200168512 1.2开关磁阻电机调速系统概述 PAGEREF _Toc200168512 \h 2 HYPERLINK \l _Toc200168513 1.2.1开关磁阻电机的基本结构和原理 PAGEREF _Toc200168513 \h 2 HYPERLINK \l _Toc200168514 1.2.2 SRD系统的组成 PAGEREF _Toc200168514 \h 5 HYPERLINK \l _Toc200168515 1.2.3 SRD系统的特点和优点 PAGEREF _Toc200168515 \h 6 HYPERLINK \l _Toc200168520 1.3开关磁阻电机调速系统的研究和发展方向 PAGEREF _Toc200168520 \h 7 HYPERLINK \l _Toc200168521 1.4本设计要做的工作 PAGEREF _Toc200168521 \h 8 HYPERLINK \l _Toc200168522 第二章 SR电机数学模型的建立 PAGEREF _Toc200168522 \h 9 HYPERLINK \l _Toc200168523 2.1 SR电机的模型 PAGEREF _Toc200168523 \h 9 HYPERLINK \l _Toc200168524 2.1.1建立模型常用的方法 PAGEREF _Toc200168524 \h 9 HYPERLINK \l _Toc200168525 2.1.2 SR电机的方程 PAGEREF _Toc200168525 \h 10 HYPERLINK \l _Toc200168531 2.2 SR电机系统的线性分析 PAGEREF _Toc200168531 \h 12 HYPERLINK \l _Toc200168532 2.2.1电感与转子位置角的关系分析 PAGEREF _Toc200168532 \h 12 HYPERLINK \l _Toc200168533 2.2.2基于线性模型的绕组电流分析 PAGEREF _Toc200168533 \h 14 HYPERLI
