The Extended kalman filter (EKF) has been found wide application in the sensorless control of induction motor (IM) because of its good steady and dynamic behaviour,disturbance resistance, and fast convergence. This paper presents a novel speed sensor

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
