Keywords: the two systems of closed circuit of direct current of speed adjustment; armature reversible; the emulation of MATLAB/SIMULINK Ⅱ  目 录 TOC \o 1-1 \h \z \u HYPERLINK \l _Toc328779631 1 绪论 PAGEREF _Toc328779631 \h 5 HYPERLINK \l _Toc328779632 2 理论分析 PAGEREF _Toc328779632 \h 5 HYPERLINK \l _Toc328779633 3 仿真软件结构设计 PAGEREF _Toc328779633 \h 8 HYPERLINK \l _Toc328779634 4 软件仿真 PAGEREF _Toc328779634 \h 10 HYPERLINK \l _Toc328779635 5 总结 PAGEREF _Toc328779635 \h 11 HYPERLINK \l _Toc328779636 6 意见与建议 PAGEREF _Toc328779636 \h 12 HYPERLINK \l _Toc328779637 7 参考文献 PAGEREF _Toc328779637 \h 12 1 绪论 逻辑无环流V-M可逆直流调速系统设计包括：1主电路的设计，2触发电路的
