| 摘 要： | 为了研究异步电机矢量控制系统,本文提出了应用电流模型设计Kalman滤波转子磁链观测器的新思路。为一台模型样机设计了基于电流模型的Kalman滤波转子磁链观测器,并设计了基于异步电机全阶模型的Kalman滤波转子磁链观测器,还迚行了对比研究,结果表明,两者的估计精度相当。可见,本文所提的基于电流模型的Kalman滤波转子磁链观测器是有效的、可行的。由于其状态方程的维数降低,它比基于全阶方程的Kalman滤波转子磁链观测器更适宜于在线观测。

| Abstract: | This paper proposed a novel method of rotor flux linkage observer of Kalman filtering based on current model to investigate vector control system of induction motors. This paper designed a rotor flux linkage observer of Kalman filtering based on current model on a sample of 1.1kW, 4p induction motor. Also a rotor flux linkage observer of Kalman filtering based on full-order model was designed as comparison. Studies show that the difference of estimation precision between these two methods is small. So this method is valid and feasible. Considering the lower order, so rotor flux linkage observer of Kalman filtering based on current model is more suitable for on-line estimation. |
