Abstract

It is common to optimize the propulsion control system through a so-called tuning process that modifies the parameter values of the propulsion control software during a ship commissioning. However, during this process, if the error of the initial setting value is large, the tuning time may take too long, or the propulsion equipment can be seriously damaged. Therefore, we conducted research on the design of a propulsion controller that applied a Processor lever controller even for inexperienced people with relatively little experience in tuning propulsion control software to be able to reduce the tuning time while protecting the propulsion system. Through simulation, by comparing the execution result of propulsion control lever commands through the PI controller without applying the Processor lever controller. We analyzed the improvement of the Overshoot and propulsion performance. The simulation results showed that the safety of the propulsion system increased because Overshoot of approximately 9.74%, which occurred when the Processor lever function was not applied.

함정 추진제어시스템은 축계와 추진엔진의 과토크 및 과부하를 방지하면서 함정 작전요구성능을 만족할 수 있는 효율적인 제어로직 적용이 필수적이다. 이에 따라 함정 시운전 기간 중 추진제어기의 파라미터 값을 수정하는 이른바 튜닝(tuning)과정을 거쳐 제어체계를 최적화 하는 것이 일반적이다. 그러나 이러한 과정에서 초기 설정 값의 오차가 큰 경우 튜닝 시간이 과도하게 소요되거나 오버토크, 오버스피드 및 과출력으로 인해 추진 장비에 손상을 초래할 수 있다. 이에 본 논문에서는 함정 추진체계를 보호하면서 비교적 추진제어기 소프트웨어의 튜닝 경험이 적은 비숙련자도 함정 추진체계를 보호하면서 튜닝시간을 단축할 수 있는 프로세서 레버 제어기 적용을 제안한다. 프로세서 레버 제어기 성능 검증을 위해 시뮬레이션을 활용하여 프로세서 레버 제어기를 적용한 결과와 PI제어기만 적용한 결과를 비교하여 제어 특성 및 추진성능을 분석하였다. 시뮬레이션 결과 프로세서 레버 제어기 기능을 미적용 시 발생하였던 9.74%의 과도응답이 발생하지 않아 추진체계의 안정성을 높일 수 있었으나, 시스템의 응답성이 늦어짐에 따라 함정 추진성능(가속능력)이 감소하였다. 이러한 추진성능의 저하는 프로세서 레버 제어기의 파라미터 값을 조정하여 안정적으로 해결하였다.
