본 논문은 산업용 전동기 시스템의 속도제어기에서 계단(Step)입력에 대한 속도의 오버슈트를 억제하는 새로운 방식의 반와인드업(Anti-windup)기법을 소개한다. 비례(P)제어기에서 비례적분(PI)제어기로의 전환 시점에 적분기가 적절한 초기값을 가지게 하여 오버슈트를 상쇄 시키고 빠른 응답 시간을 가지게 하였다. 시뮬레이션을 통하여 제안된 방법의 타당성을 확인하고 기존의 반와인드업 기법과 비교하여 그 우수성을 검증하였다.

The simplified dynamic models of the timer assembly in the diesel engine fuel injection system were developed. The first order system with time delay was assumed and the various parameters in this model were obtained by experimental data. These simplified dynamic models were used for the development of control algorithm of the injection timing control system. The PI control algorithm was modified to include the anti-windup property and disturbance compensation. This modified PI control algorithm was used for the control of the injection timing. Improved control accuracy and reduced control efforts were observed.
