Abstract
본 발명은 영구자석 동기모터(44)의 전류제어장치에 관한 것으로, 상기 속도제어신호를 입력하여 미리 저장된 상기 쇄교자속파형을 기준으로 전류지령을 발생하는 전류지령 발생부(21)와; 상기 전류지령 발생부(21)의 출력을 궤환된 전류와 비교하여 제어전류를 출력하는 비례적분 전류제어기(22) ; 상기 비례적분 전류제어기(22)의 출력을 입력하여 영구자석 동기모터(44)의 역기전력을 보상하는 역기전력보상부(23); 상기 역기전력보상부(23)의 출력을 입력하여 3상의 펄스폭변조신호를 출력하는 펄스폭변조부(24) ; 및 상기 영구자석 동기모터의 권선에 흐르는 전류를 검출하여 디지탈 변환 후 3상/2상 좌표를 변환하여 궤환전류를 출력하는 좌표변환부(25)를 구비하여 측정된 쇄교자속으로부터 계산한 전류지령에 의해 토크 리플을 제거한다.The present invention relates to a current control device for a permanent magnet synchronous motor (44), comprising: a current command generation unit (21) for inputting the speed control signal to generate a current command based on a previously stored linkage flux waveform; A proportional integral current controller 22 for outputting a control current by comparing the output of the current command generator 21 with the feedback current; A back electromotive force compensator (23) for inputting the output of the proportional integral current controller (22) to compensate for back electromotive force of the permanent magnet synchronous motor (44); A pulse width modulator 24 for outputting a three-phase pulse width modulated signal by inputting the output of the counter electromotive force compensator 23; And a coordinate conversion unit 25 which detects a current flowing in the winding of the permanent magnet synchronous motor, converts three-phase and two-phase coordinates after digital conversion, and outputs a feedback current. Torque ripple is eliminated by
