| 摘 要： | 设计了转速、电流双闭环的变频调速控制系统。利用MATLAB/Simulink仿真软件,搭建了三相异步电机转速、电流双闭环SPWM变频调速系统。通过调节各模块的设置参数,得到了理想的仿真波形,实现了该系统的仿真。通过将仿真结果与开环变频电路仿真结果相比较可以看出,闭环变频调速系统在调速能力和抵抗负载扰动等方面比开环系统有更好的动态特性,并且有较宽的调速范围。说明了双闭环调速SPWM变频调速系统良好的调速特性。

| Abstract: | A speed and current double closed-loop adjustable speed with SPWM variable frequency controlling system is designed by MATLAB/SIMULINK software in this paper.By adjusting simulation parameters in each model,we get perfect simulation waveform.Compared with open-loop,double closed-loop have better dynamic characteristic in adjustable speed and resisting load disturb.The simulation results show clearly that the speed and current double closed-loop adjustable speed with SPWM variable frequency system have better characteristic. |
