Currently has been successfully used in electric vehicle drive system, household appliances, industrial application, servo system, high-speed drive, aerospace, etc, become ac motor speed control system, dc motor speed control system and brushless dc motor control system of strong competitors. Switch reluctance motor driving speed in the field has been widely used in power, but also more and more field, caused a lot of experts and scholars of interest. This paper first introduces a switched reluctance motor speed control system (SRD) history, advantages, research direction and application, Condition, and the SRM features and electromagnetic principle, from the basic laws of electromagnetic, the principle and the related theory SRD). Using the mathematic model and the model, SRM SRD system model, the current controller model, inverter model, the Angle control model, and through MATLAB simulation and comparison analysis and simulation of the ideal mathematical model. Keywords: SRG, The mathematical model PAGE 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc263411789 第1章 绪论 PAGEREF _Toc263411789 \h 1 HYPERLINK \l _Toc263411790 1.1 开关磁阻调速电动机发展简介 PAGEREF _Toc263411790 \h 1 HYPERLINK \l _Toc263411791 1.2 开关磁阻电机的特点 PAGEREF _Toc263411791 \h 2 HYPERLINK \l _Toc263411792 1.3 开关磁阻调速电动机的研究动向及应用 PAGEREF _Toc263411792 \h 3
