개선된 순시무효전력 보상기를 이용한 IPMSM의 센서없는 속도제어
나재두(Jae Du La) 대한전기학회 2018 전기학회논문지 Vol.67 No.10
A improving sensorless compensator for the IPMSM(Interior Permanent Magnet Synchronous Motor) drive system is proposed. Generally, the motor drive system is required the robust parameter variation and disturbance. The speed estimation methods of the conventional IRP(Instantaneous Reactive Power) compensator is improved by the speed estimation techniques of the current model observer with the proposed instantaneous reactive power compensator. Performance evaluations of the novel speed error compensator and sensorless control system are carried out by the experiments.
