Position Sensorless Control of Switched Reluctance Motor Using State Observer

This paper studies the position sensorless control of a switched reluctance motor which used state observer. The position sensorless control of a switched reluctance motor is realized by estimating the flux linkage, angular velocity, and rotor position using the state observer obtained from linear state equation. It verifies with simulation that good position estimation can be performed also not only in linear region but in saturation region.
