摘要直流调速系统的在工业中的应用很广泛, 也是沟通调速系统的基础。直流调速系统用双闭环结构时控制效果最好, 为此本文对双闭环直流调速系统进行了讨论, 重点对控制部分展开讨论。分析调速系统的稳态和动态结构, 建立双闭环直流调速系统的数学模型, 经过全面分析根据双闭环直流调速系统的控制要求将电流和转速都设计为比例积分调节器, 并设计了电流和转速调节器的参数。对经典双闭环系统进行分析的同时, 为了能得到合理的设计参数, 用 MATLAB 软件对电流环和转速环的设计举例进行了仿真, 经过比较说明了直流调速系统的特性。 关键词: 双闭环直流调速系统; 比例积分调节器 ; MATLAB ABSTRACTDC servo system is widely used in the industry, and is the fadation of AC servo System.The DC servo system can be controled well with double-closed system.In this paper double-closed loop DC servo system is studied,the importance of zhe study is the control section.analysis of the static and dynamic of speed control system,and establishing a double-closed loop DC system mathematical model. PI controler is designed for both the current and speed regulator, and design current and speed regulator parameters. When analysis of the classical double-loop system, in order to get a reasonable design parameters. MATLAB software has been selected to simulate parameters of the system which has been choosen,with a comparison to show the characteristics ofDC Control system.KEY WORDS: Double-closed loop DC servo system ;PI controller;MATLAB目 录第一章 绪 论...............................................11.1 课题背景、 进展及意义..................................11.2 课题的主要任务及内容................................................................................................11.3 论文的内容安排及主要工作...............................1第二章 直流调速系统理论讨论和方案确定......................32.1 双闭环调速系统的工作原理...............................32.1.1 转速控制的要求和调速指标......
