Design and Implementation of Double-Loop DC Speed Control Simulation System

面向电气原理结构图仿真方法无需编程且不需推导系统的动态数学模型,系统的建模过程接近实际系统的搭建过程,仿真结果的可信度很高.本文以工程上用的最多的双闭环直流调速系统为例,详细介绍系统建模过程、元器件参数设置及建模注意的问题,并对仿真结果进行分析.掌握该方法,有助于自动化专业学生对所学理论的理解,提高其实践动手能力,对今后的课程设计和毕业设计具有重要指导意义.

The simulation method of using schematic diagram need neither programming nor deriving mathematical model of the dynamic system,while modeling being close to the actual process,so the credibility of simulation results is higher.Taking an example for double-loop DC adjustabled-speed system,which is widely used in the electrical engineering,this paper introduces the modeling process,Components parameter setting,the issue of modeling and analyzing the simulation results in the last.Mastering the method,it will be useful for students to understand the theory,to improve their practical capacity,and it is of important significance for design of curriculum and graduation in a later.
