| 摘 要： | 本文介绍了一种改进的定子磁链观测方法,并在此基础上设计了转速估算器。磁链观测器和速度估算器结合起来应用于无速度传感器的矢量控制系统。通过Matlab仿真试验,得到转速、转矩、定子电流及其磁链等的仿真波形。仿真结果验证了该控制方法具有较好的动态响应和较强的鲁棒性。

| Abstract: | A modified voltage model flux observer is presented, and a new speed estimator is proposed based on flux observer method. Then combined with the flux observer and speed observer, a speed sensorless vector control system for induction is presented. Through the experiment emulated by the Matlab, the waveform of rotor speed, electromagnetic torque and stator flux are given. The simulation results confirm this control method have higher dynamic response and comparatively strong robust. |
