摘    要:将一种全阶磁链观测器引用到异步电动机的直接转子磁场定向中,研究其运行时受电机参数变化的影响.借鉴频率响应法,对比常见的电流模型磁链观测器和电压模型磁链观测器,采用数据拟合的方法对电机参数变化下的磁链观测值进行拟合,得到其参数鲁棒性结论.仿真结果表明,应用该全阶磁链观测器可以克服电机转子电阻变化的影响,减小电机定子电阻变...

关 键 词:异步电动机  全阶磁链观测器  磁场定向  转子电阻  参数鲁棒性

Abstract:A full-order closed-loop rotor flux estimator was introduced into the direct field oriented control(DFOC) in an induction motor,and the observer precision affected by motor parameter was investigated.The normal current flux observer and voltage flux observer were compared by frequency response method.Amplitude-and-phase-frequency characteristic curve method of linear time-invariant system was used to simulate the parameter robustness of the proposed full order flux observer.The simulation results indicated ...
Keywords:induction motor  full-order flux observer  magnetic field oriented control  rotor resistance  parameter robustness
