| 摘 要： | 为了实现矢量控制系统中异步电动机转速的闭环控制和磁场定向,对基于模型参考自适应系统(model reference adaptive system,MRAS)的无速度传感器矢量控制系统进行研究。从异步电机端测量得到的电压和电流来估算电机转速,在异步电动机无速度传感器矢量控制算法中,采用电流模型和电压模型进行磁链估算,基于MRAS方法构建异步电动机转子转速辨识模型,并在Matlab/Simulink中建立了异步电动机无速度传感器矢量控制仿真系统。仿真结果表明:该系统具有良好的动静态特性和稳定性。

| Abstract: | Speed-less sensor vector control system based on model reference adaptive system(MRAS) is studied to implement the closed-loop control of speed and field oriented control of induction motor in vector control system.Use voltage and current from asynchronous motor terminal estimate motor rotation speed.In asynchronous motor speed-less sensor vector control algorithm,use current model and voltage model to carry out magnetism linkage estimation,establish asynchronous motor rotor rotation speed diagnosis model based on MRAS method,then construct asynchronous motor speed-less sensor vector control simulation system in Matlab/Simulink.The simulation results show that this system has high dynamic and static performance and stability. |
