This paper describes a Model Reference Adaptive System (MRAS) based scheme using a multilayer Recurrent Neural Network (RNN) for online speed estimation of sensorless vector controlled induction motor drive.

永磁同步电机无速度传感器控制，基于EKF实现(Speed Sensorless Control of Permanent Magnet Synchronous Motor Based on EKF)

基于EKF的三相PMSM无传感器矢量控制框图，EKF算法采用s函数进行编写，函数命名为EKF。其中，输入为电机在静止坐标系下的钉子电压和定子电流，输出为定子电流估计值，转速和转子位置(Based on EKF's three-phase PMSM sensorless vector control block diagram, EKF algorithm uses s function to write, and the function is named EKF. Among them, th
