this paper presents a sensorless system drive on primary flux oriented control (pfoc) and secondary flux oriented control (sfoc) for the linear induction motor (lim) with taking into account end effect. extended kalman filter (ekf) is applied to estimate lim speed by measuring motor voltages and currents. in order to achieve desirable dynamic and robustness motor performance instead of traditio...

formance is analyzed for flux vector and indirect field oriented controllers. A new technique-the back electromagnetic force (BEMF) detector-for reducing the adverse effects of stator resistance on field oriented control is presented and evaluated through simulation and experimental results. The BEMF detector is shown to reduce the impact of the stator resistance and provides a stator resistanc...
