摘要
介绍一种采用外推卡尔曼滤波实现对转速与转子位置观测的控制方案 ,对外推卡尔曼滤波在无转子位置检测磁场定向控制中的应用原理进行了详细的分析 ,并实现了对转速与转子位置的解耦 ,最后给出了利用扩展卡尔曼滤波实现永磁同步电动机无转子位置检测磁场定向控制系统的仿真结果 。
This paper introduces a control scheme which uses extended kalman filter (EKF) for estimating the speed and rotor position,the principle of using EKF in field-oriented control (FOC) system is analysed in detail,and the estimations of speed and rotor position are decouple successfully.At last,the simulate results of the FOC system using EKF of PMSM are given to prove the feasibility of EKF.
