摘要
将Matlab/Simulink引入课程的虚拟实验教学之中。利用Simulink建立了双闭环控制的绕线式异步电机串级调速系统仿真模型,给出了仿真参数,利用仿真结果分析了串级调速系统的启动过程、突加负载和转速给定值改变时的动态调节过程,验证了该调速系统仿真模型的正确性。在实验教学中,Simulink仿真模型辅助学生对系统动态调节过程的理解、建立系统级控制思想,也可用于研究和开发异步电机串级调速系统。
The Matlab/Simulink software is presented into the course’s virtual experiment teaching.The simulation model of wound-rotor asynchronous motor cascade speed control system controlled by dual-loop is established. Simultaneously,the simulation parameters of the proposed simulation model are given respectively.The starting process, the loading process,and the speed dynamically adj usting process when the voltage given value changes,are analyzed in detail based on the simulation results.The feasibility of the cascade speed control system is verified by the simulation results.In the experiment teaching,the Simulink simulation model will help students understand the dynamic adjustment process,establish the system-level control idea.It can also be used for research and development on wound-rotor asynchronous motor cascade speed control system.
