An Application of the Extended Kalman Filter for a Sensorless Stepper Motor Drive Working With Long Cables

In this paper, an approach is proposed for the application of an extended Kalman filter (EKF) to a sensorless stepper motor drive, when the motor is separated from its drive by long cables. When the long cables and high-frequency pulsewidth-modulated control voltage signals are used together, the electrical signals differ greatly between the motor and drive… CONTINUE READING
