摘要
针对级联高压变频器异步电机无速度传感器矢量控制,研究了一种基于两相旋转坐标系下模型参考自适应系统(MRAS)来辨识异步电机转速的方案。仿真和实验结果表明,该转速辨识方案结构简单,易于实现,能准确地估计电机的磁链和转速。
According to speed sensorless vector control of asynchronous motor based on cascaded high voltage convert- er, a model reference adaptive system （MR/kS） implemented in two axis rotating reference frame is studied to identify the rotor speed of an asynchronous motor.Simulation and experimental results show that the method of speed identifi- cation is easy to realize, and can estimate the flux and speed with good accuracy.
