によりガスエンジン４に供給する燃焼ガス量を調
節しガスエンジン４の運転を制御する。Conventional Structure and Problems There is a conventional control device for a gas engine as shown in FIG. In the figure, 4 is a gas engine that uses combustion gas as fuel. A starter motor 6 is connected to the gas engine 4 via a centrifugal clutch 5, and is turned on and off by a switch 7.
It will be turned off. 1 is a solenoid valve that cuts off and on the supply of combustion gas. An actuator 2 adjusts the amount of combustion gas supplied from the solenoid valve 1 to the gas engine 4, and its movement is controlled by the engine governor 3. The control circuit 8 drives the starter 6 by turning on the switch 7, and also opens and closes the solenoid valve 1. Furthermore, in order to obtain the required rotational speed of the gas engine 4, the amount of combustion gas supplied to the gas engine 4 is adjusted by outputting a voltage to the engine governor 3, thereby controlling the operation of the gas engine 4.
エンジンガバナ３は制御回路８からの設定電圧
によりアクチユエータ２を制御し、燃焼ガス量を
目標値に規制するわけであるが、急速に目標値へ
近づけると、第２図のようにオーバーシユートや
アンダーシユートを生じ振動する。 The engine governor 3 controls the actuator 2 using the set voltage from the control circuit 8 and regulates the amount of combustion gas to the target value, but if it approaches the target value rapidly, overshoot or It causes undershoot and vibration.

回路８が設定電圧を出してからアクチユエータ２
が目標値に達するまでに遅れを生じる。 If the aquatuator 2 causes such undershoot when changing the target value while the gas engine 4 is operating, the supply of combustion gas to the gas engine 4 will temporarily stop during low rotational speed operation, and the engine will stop. There is a risk of it being stored away. Therefore, the engine governor 3 controls the actuator 2 so that the target value is gradually reached as shown in FIG. As a result, after the control circuit 8 outputs the set voltage, the actuator 2
There will be a delay before reaching the target value.

て遅れを生じている。 FIG. 4 shows the starting of a conventional gas engine control device. The control circuit 8 simultaneously outputs an opening output S1 of the solenoid valve 1, a drive output S2 of the starter 6, and a set voltage S3 to the engine governor 3. S4 is the movement of the actuator 2, and as described above, there is a delay with respect to the set voltage S3 to the engine governor 3 until the target value is reached.
アクチユエータ２が目標値に達し、ガスエンジ
ン４が起動すると遠心クラツチ５がはずれ、スタ
ータ６への通電を停止する。 When the actuator 2 reaches the target value and the gas engine 4 is started, the centrifugal clutch 5 is disengaged and the energization to the starter 6 is stopped.
ところがこの従来の制御では、エンジン始動動

また始動時のスタータモータによる騒音も長い欠
点を有していた。 However, with this conventional control, it takes time to start the engine until the gas engine 4 is completely started due to the delay of the engine governor 3. This reduces wear and tear on the starter motor and
Furthermore, the noise caused by the starter motor during startup has also been a long-standing drawback.
