Speed Sensorless Control Strategy for Six-Phase Linear Induction Motor Based on the Dual Reduced-Order Serial Extended Kalman Filters

This study proposes a speed sensorless vector control strategy for the six-phase linear induction motor (SPLIM) based on the dual reduced-dimensional serial extended Kalman filters (DRDSEKFs). Firstly, the low-order mathematical model of SPLIM is obtained according to the equivalent transformation of primary voltage, current and flux components in the stationary coordinate system. Then, the state ...
