用主機関の回転数制御装置。[Scope of claim for utility model registration] P on the output side of the calculator for the command rotation speed and actual rotation speed.
In the rotation speed control device for a main marine engine, an ID controller is connected, a constant function generator is connected to the input side of the PID controller, and the output side is connected to the fuel supply actuator via the arithmetic unit. A no-load function generator for each of the PID controllers is provided between the input side of the PID controller and the constant function generator, and switching is made between the no-load function generator and the constant function generator. A switch is provided, and when the output of the load detector that detects the actuator position from the actual rotation speed and the output of the actuator position become equal to or less than the output setting value of the arithmetic unit, the switch is activated from the constant function generator. A rotation speed control device for a main marine engine, characterized in that it is connected to a comparator that generates a signal for switching to a load function generator.
