An Excitation Position Dectecting Method Using Phase Current for Sensorless Control of SRM

SRM의 상전류를 이용한 센서리스 방식의 여자시기 검출기법

This paper describes a novel method of detecting excitation position in Switched Reluctance Motor(SRM) drive. Some strategics for position sensorless control methods of the SRM include the measurement of phase current. The principle of the rotor position estimation is based on the defection of phase current according to rotor position. This sensorless method is very simple to detect excitation position estimation and gives efficient control of drive system. The suggested method is verified by some simulations and experimental tests
