Position Sensorless Implementation for a Linear Switched Reluctance Machine
The development of an add-on sensorless position estimator for a 4.8 m Linear Switched Reluctance Machine (LSRM) with minimal modifications to the transducer-based controller is investigated for the first time in this study. LSRMs require position feedback for closed-loop control but present a low …

Position Estimation in Switched Reluctance Motor Drives Using the First Switching Harmonics of Phase Voltage and Current
Position estimation using only active phase voltage and current is presented to perform high accuracy position sensorless control of a SRM drive. By extracting the amplitude of the first switching harmonic terms of phase voltage and current for a PWM period through Fourier analysis, flux-linkage …
