Study on Controller Design of AC Servo Permanent Magnet Synchronous Motor by Matrix Converter : Speed Controller

매트릭스 컨버터에 의한 AC 서보 영구자석형 동기전동기의 제어기 설계에 대한 고찰 : 속도제어기

This paper deals with the design for speed controller to drive PMSM by matrix converter without DC-link circuit as the power conversion system of AC servo motor drive. To design the speed controller of PMSM drive, the closed-loop transfer function of speed controller is calculated and then the frequency-domain response characteristics are analyzed by bode plot using Matlab. Based on the results by bode plot, the speed control gains are determined. As the real effects of controller designed in the frequency-domain display in the time-domain, the performance of speed controller is confirmed by the step response of speed controller. The design examples are shown and its validity of the design method mentioned in the paper is verified through PSIM simulation.
