지령회전수와 실회전수와의 편차를 구하는 연산기와 그 편차를 비례, 적분, 미분조작하여 작동기의 위치지령으로서 출력하는 PID 제어기와 지령회전수등에 대한 작동기위치지령의 상한을 정하여 상기 작동기위치지령을 통과시키는 제1리미터와 그 작동기위치지령에 의해 작동하고 연료랙업위치를 제어하는 작동기를 구비한 선박용 주기관 제어장치에 있어서, 상기 실회전수를 그 주기관의 정격회전수에 가까운 어떤 기준회전수와 비교하여, 실회전수가 기준회전수 미만일때는 보지신호를 출력하며, 또한 실회전수가 기준회전수 이상이 되면 절환신호를 출력하는 비교기와, 상기 보지신호에 의해 PID 제어기의 각정수를 통상의 값으로하여 상기 절환신호에 의거 PID 제어기의 각정수를 상기 통상의 값보다도 고감도의 값으로 절환시키는 제1스위치와, 상기 보지신호에 의거 PID 제어기로부터의 작동기위치지령을 제1리미터를 거쳐 작동기로 전달시켜, 상기 절환신호에 의해 PID 제어기로부터의 작동기위치지령을 제1리미터 및 별개의 제2리미터를 거쳐 작동기로 전달시키는 제2스위치를 설치하여, 상기 제2리미터는 감소방향 또는 현상유지의 작동기위치지령외에는 통과시키지 않는 것으로 하는 것을 특징으로 하는 선박용 주기관 제어장치.The actuator position command is determined by setting the upper limit of the actuator position command for the PID controller and the command rotation speed that outputs the position command of the actuator by calculating the deviation between the command rotation speed and the actual rotation speed and proportionally, integrally, and derivative the deviations. A ship main engine control device having an actuator for operating a fuel rack-up position operated by a first limiter and an actuator position command for passing through the engine, wherein the actual rotational speed is any reference rotation close to the rated rotational speed of the main engine. The comparator outputs a holding signal when the actual rotational speed is less than the reference rotational speed, and outputs a switching signal when the actual rotational speed is more than the reference rotational speed. A first switch for switching each constant of the PID controller to a value having a higher sensitivity than the normal value based on the switching signal as a value; The actuator position command from the PID controller is transmitted to the actuator via the first limiter based on the holding signal, and the actuator position command from the PID controller is transmitted to the actuator via the first limiter and a separate second limiter by the switching signal. The second limiter is provided so that the second limiter does not pass outside the actuator position command in the decreasing direction or the status maintaining. 제1항에 있어서 기준회전수를 그 주기관의 전격회전수보다 크고 오버스피드회전수보다는 작게 설정하는 것을 특징으로 하는 선박용 주기관 제어장치.The ship main engine control apparatus according to claim 1, wherein the reference rotational speed is set larger than the electric rotational speed of the main engine and smaller than the overspeed rotational speed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
