摘要
在电力电子和电力拖动控制系统仿真实验教学中针对矢量控制理论在交流调速系统中的应用,通过MATLAB/Simulink仿真工具建立了带有转矩、转速磁链闭环的无传感器交流异步电机矢量控制系统,并对矢量控制系统中的异步电机启动、负载变化、正反转等动态过程中的磁链、速度、转矩进行分析,来验证控制系统仿真模型的正确性。同时通过仿真实验教学不仅拓展了课堂理论知识,也增强了学生对矢量控制理论的理解和应用,提高了教学质量。
In the simulation experiment teaching of power electronics and electric drive control system,aiming at the application of vector control theory in AC speed regulation system,the vector control system of sensorless AC asynchronous motor with torque and speed flux closed-loop is established based on MATLAB/Simulink,and the flux,speed and torque in the dynamic process of the vector control system,such as starting,load change,forward and reverse rotation,are analyzed to verify the correctness of the simulation model of the control system.At the same time,the simulation experiment teaching not only expands the theoretical knowledge of the classroom,but also enhances the students'understanding and application of vector control theory,and improves the teaching quality.
