Dc double closed loop speed regulation system set up two regulator, speed regulator (ASR) and current regulator (ACR), adjusting the rotational speed and current respectively. In this paper, the design of dc double closed loop speed regulation system is analyzed, the principle of dc double closed loop speed regulation system with some instructions, introduces the design of main circuit, detection circuit, the design of the current regulator and speed regulator is introduced and some parameters selection and calculation, to make it satisfy the standard of engineering design parameters. Keywords: current regulator dc double closed loop speed regulation system of speed regulator 页 PAGE \* Arabic4 目 录 TOC \o 1-3 \h \u HYPERLINK \l _Toc12075 0 绪论 1 1 总体设计方案 HYPERLINK \l _Toc1091 2 HYPERLINK \l _Toc26436 1.1方案比较 HYPERLINK \l _Toc6223 2 HYPERLINK \l _Toc13368 1.2方案论证 3 HYPERLINK \l _Toc23510 1.3方案选择 7 1 HYPERLINK \l _Toc6558 .4设计要求 4 2 单元模块设计 HYPERLINK \l _Toc3662 5 HYPERLINK \l _Toc595 2.1转速给定电路设计 5 HYPERLINK \l _Toc23417 2.2转速检测电路设计 5 HYPERLINK \l _Toc28187 2.3电流检测电路设计 6 HYPERLINK \l _Toc25317 2.4整流及晶闸管的保护 7 HYPERLINK \l _Toc10661 2.4.1过电压保护和di/dt限制 8 HYPERLINK \l _Toc9342 2.4.2过电流保护和di/dt限制 8
