基于Matlab的单相异步电机调速系统仿真设计

Simulation design of the frequency conversion timing system of single-phase asynchronous motors based on Matlab

在分析单相异步电机数学模型的基础上,基于Matlab/Simulink环境,建立电机的矢量仿真模型。该模型利用PID及逆变器等控制器件,通过交流-直流-交流进行变频后,来改变电动机的转速,实现异步电动机矢量控制变频调速。仿真结果表明:在Kp=2、Ki=20、Kd=0.1时,调速处于较佳的状态下,调速性能较好。

The mathematical model of single-phase asynchronous motor is analysised.The simulation model of asynchronous motor vector is created based on the Matlab/Simulink environment.The model uses the PID and the inverter control device to change the motor speed,through a method called AC-DC-AC inverter.Simulation results show that： when Kp=2,Ki =20,Kd=0.1,the speed is better speed performance.
