영문 초록

The propulsion marine diesel engine have been widely applied with a mechanical-hydraulic governor to control the ship speed for long time. Recently, it was very difficult for the mechanical-hydraulic governor to control the speed of engine under the condition of long stroke, low speed and a few cylinder because of jiggling and hunting. In order to remove these difficulties the digital governor system is adapted for the speed control of a low speed marine diesel engine. But there is the problem of confidence in digital governor systems due to low reliability of electronic parts under the bad condition such as high temperature, salty, watery air and intensive viberation in engine room. To solve the these problems of control system, the performance improvement of mechanical-hydraulic governor is required. In this paper, it is analyzed how much influence is given by a parameter variation of mechanical hydraulic governor for the speed control system by utilizing the Nichols chart, and the optimal parameters are investigated through the computer simulations. The performance improvement of a conventional mechanical hydraulic governor is confirmed to be possible by the above studies.
