PM BLDC 모터의 PLL 알고리즘을 사용한 정밀속도제어 및 센서리스 기법 = Precise Speed Control and Sensorless Technique of PM BLDC Motor Using the PLL Algorithm

다국어 초록 (Multilingual Abstract)

Brushless DC Motor(PM BLDCM) is widely used in industrial applications due to its high efficiency and power density. In order to increase reliability and reduce system cost this Paper studies particularly applicable method for sensorless PM BLDCM drive system. The resulting third harmonic signal keeps a constant phase relationship with the rotor flux for any motor speed and load condition and is practically free of noise that can be introduced by the inverter here is not sensitive to filtering switching, making this a robust sensing method. As a result the method described here is not sensitive to filtering delays, allowing the motor to achieve a good performance over a wide speed range. In addition, a simple starting method and a speed estimation approach are also proposed.
