Speed Estimation of High-Speed Hysteresis Motor Based on Extended Kalman Filter
Abstract: High-speed hysteresis motors are used in special industries such as medical centrifuges and gyroscopes. In spite of that, they are synchronous motors in some situations they may work in asynchronous speed. So, for reliable performance of hysteresis motor, closed loop control strategies are employed. On this way, speed/position of rotor must be known. Due to difficulty of using the speed sensors in high-speed hysteresis motor drives, employing the speed estimation …
