摘要

分析Matlab/Simulink仿真技术在转速单闭环直流调速系统中的应用.考虑了转速有静差和无静差两种情况,采用面向电气原理结构图的仿真方法建立仿真模型;给出主电路和控制电路的参数设置方法,同时改变转速调节器的参数设置,对单闭环直流调速系统的调速性能进行仿真实验分析,并给出直流电动机的转速和电枢电流仿真波形.实验结果表明,单闭环直流调速系统的调速性能仿真结果与理论推导的调速性能一致,对实验教学有一定的指导意义.%This paper mainly analyzes the application of simulation technique of Matlab/Simulink to rotating speed single closed loop DC speed control system.utilizing the simulation method of facing electric principle construction diagram based on the possible cases of static error and no static error,the paper proposes the parameter setting methods of main circuit and control circuit.At the same time,the simulation experimental analysis of the speed performance of the single-losed loop DC motor control system is made with changes of the parameter setting of speed regulator.The simulation waves of speed and current of DC motor are also given out.The experimental results show that the simulation results of speed performance of single closed loop DC motor are consistent with those obtained from theory,and this system offers guidance for experimental teaching.
