전기유압식 조속기를 가진 디젤기관의 속도제어 = On the Speed Control of the Diesel Engine with a Electro-Hydraulic Governor

다국어 초록 (Multilingual Abstract)

Marine propulsion diesel engines which have a mechanical-hydraulic governor have been widely used to control engine speed until now. Recently, it was very difficult for this governor to regulate the speed of high power engines with a long stroke and low speed, because of the jiggling caused by the rough fluctuation of rotating torque as well as the hunting by long dead time occurring in the fuel combustion process.
In this paper, an electro-hydraulic governor which utilized PID and fuzzy control algorithms is suggested to compensate for the faults of the mechanical-hydraulic governor. The Nichols chart is used to investigate the influence of parameters related to the hydraulic actuator and ship propulsion system. The computer simulation shows that the electro-hydraulic governor with PID and fuzzy logic controller has good performance improvement.
