摘要
针对三相异步伺服电机无速度传感器矢量控制下转速辨识问题,提出一种基于无功功率模型参考自适应的异步电机转速辨识新方法。该方法采用了基于反电动势模型参考自适应的定子电阻辨识方法来实时追踪定子电阻参数值的变化情况,并将定子电阻估计值作用于转子磁链观测器,以消除定子电阻设定值和实际值的偏差对转子磁链的影响,最后把观测出的转子磁链传递至无功功率模型参考自适应的可调模型,解决了三相异步伺服电机无速度传感器转速辨识精度低问题,提高了系统转速动态辨识能力。仿真结果证明了该方法的有效性和可行性。
A new method based on reactive power model is proposed to identify asynchronous motor speed identification based on reactive power model. The method adopted is based on back emf model reference adaptive stator resistance identification approach to real-time tracking of the stator resistance changes of the parameter values, and the stator resistance estimation function to the rotor flux observer, in order to eliminate the deviation of the stator resistance value and actual value, the influence of rotor flux finally, the observation of the rotor flux linkage to reactive power model reference adaptive adjustable model, solved the three-phase asynchronous speed sensorless speed low identification precision of servo motor problem, improve the system dynamic recognition speed. Simulation results show the effectiveness and feasibility of the proposed method.
