극 배치 기법을 이용한 표면 부착형 영구자석 동기 전동기의 고속 토크 제어

In this paper we propose a novel torque control method for permanent magnet synchronous motors using the SVPWM (Space Vector PWM). The control law is described in the rotating d-q frame and is devised to track a given reference flux with which the reference torque is generated. The key feature of the proposed control is that it provides uniform dynamics with desired closed-loop poles independent of the rotating speed and the desired poles can be selected to yield a fast response with only a small amount of torque ripple.
