Description
本発明は、舶用エンジンのガバナ制御装置に関する。 The present invention relates to a marine engine governor control device.
舶用エンジンの制御では、設定された目標回転速度と実回転速度の差がなくなるようにPID制御が行われる。また、荒天時などの外乱によるプロペラ回転速度の変動を予測してPID制御のゲインを変更する構成も提案されている(特許文献1)。 In the marine engine control, PID control is performed so that the difference between the set target rotational speed and the actual rotational speed is eliminated. In addition, a configuration has been proposed in which the gain of PID control is changed by predicting fluctuations in the rotation speed of the propeller due to disturbance such as during stormy weather (Patent Document 1).
しかし、舶用エンジンのガバナ制御は、主機の回転を目標回転速度に維持する制御を行っているため、海象の影響により船体がローリングしている場合、主機の回転が目標回転速度に維持されても、プロペラの対水回転速度は一定とはならない。すなわち、船体がプロペラ回転方向にローリングする場合には、プロペラの対水回転速度は船体ローリングによる回転分速くなり、船体がプロペラ回転方向とは逆方向にローリングする場合には、プロペラの対水回転速度は、船体ローリングによる回転分遅くなる。 However, since the governor control of the marine engine performs control to maintain the rotation of the main engine at the target rotation speed, even if the hull is rolling due to the influence of sea conditions, the rotation of the main engine is maintained at the target rotation speed. The rotation speed of the propeller against water is not constant. That is, when the hull rolls in the propeller rotation direction, the propeller rotation speed is higher by the rotation due to the hull rolling, and when the hull rolls in the direction opposite to the propeller rotation direction, The speed is reduced by the amount of rotation due to hull rolling.
船体ローリングによる対水プロペラ回転速度の変動の最大値は、ローリング角度と、その周期に依存し、通常、毎分±数回転程のオーダとなる。例えば、10秒周期のローリングにおいて、ローリング角度±10度のとき、ローリングによる対水プロペラ回転速度の変動は、最大で約±1rpmとなる。プロペラ負荷は、回転速度の3乗に比例するため、例えば主機が100rpmで運転中に、対水プロペラ回転速度に±1rpm(1%)の変動があると、プロペラ負荷は、約±3%変動する。 The maximum value of the rotation speed of the water propeller due to the hull rolling depends on the rolling angle and its cycle, and is usually on the order of several rotations per minute. For example, in rolling with a period of 10 seconds, when the rolling angle is ± 10 degrees, the fluctuation of the rotational speed of the water propeller due to rolling is about ± 1 rpm at the maximum. Since the propeller load is proportional to the cube of the rotational speed, for example, if the main propeller is operating at 100 rpm and the water propeller rotational speed varies by ± 1 rpm (1%), the propeller load varies by approximately ± 3%. To do.
このような船体ローリングによる負荷変動の下、従来のように主機の回転速度を一定に維持しようとすると、ガバナ制御装置は、ローリングによる負荷変動に応じて燃料投入量を周期的に増減し、結果的に燃費の悪化を招く。 Under such load fluctuations caused by hull rolling, if the main engine speed is to be kept constant as in the past, the governor controller periodically increases or decreases the fuel input amount according to the load fluctuations caused by rolling. In particular, the fuel consumption is deteriorated.
本発明は、船体のローリングによる影響を考慮したガバナ制御を行い、燃費の改善を図ることを課題としている。 An object of the present invention is to improve the fuel consumption by performing governor control in consideration of the influence of rolling of the hull.
本発明の舶用エンジンのガバナ制御装置は、主機の実回転速度を検出する実回転速度検出手段と、船体ローリングの回転速度を検出するローリング速度検出手段とを備え、実回転速度と船体ローリングの回転速度に基づいて対水プロペラ回転速度を一定に維持することを特徴としている。 A governor control device for a marine engine according to the present invention comprises an actual rotational speed detecting means for detecting an actual rotational speed of a main engine and a rolling speed detecting means for detecting a rotational speed of a hull rolling, and the actual rotational speed and the rotation of the hull rolling. It is characterized in that the rotational speed of the water propeller is kept constant based on the speed.
ガバナ制御装置は、例えば実回転速度に船体ローリングの回転速度を加算してフィードバック制御を行う。 The governor control device performs feedback control by adding the rotational speed of the hull rolling to the actual rotational speed, for example.
また、ガバナ制御装置は、回転速度指令から船体ローリングの回転速度を差し引くことでガバナ制御を行う。この場合、従来のガバナ制御システムに大きな変更を加えることなく本発明に係る構成を付加することができる。 Further, the governor control device performs the governor control by subtracting the rotational speed of the hull rolling from the rotational speed command. In this case, the configuration according to the present invention can be added without greatly changing the conventional governor control system.
本発明の舶用エンジンのガバナ制御方法は、主機の実回転速度を検出するとともに、船体ローリングの回転速度を検出し、実回転速度と船体ローリングの回転速度に基づいて対水プロペラ回転速度を一定に維持することを特徴としている。 The governor control method for a marine engine according to the present invention detects the actual rotation speed of the main engine, detects the rotation speed of the hull rolling, and makes the rotation speed of the water propeller constant based on the actual rotation speed and the rotation speed of the hull rolling. It is characterized by maintaining.

An actual rotation speed detection means for detecting the speed and a rolling speed detection means for detecting the rotation speed of the hull rolling are provided, and the rotation speed of the propeller with respect to water is kept constant based on the actual rotation speed and the rotation speed of the rolling. It is characterized by that.
本発明によれば、船体のローリングによる影響を考慮したガバナ制御を行い、燃費の改善を図ることができる。 According to the present invention, it is possible to improve the fuel consumption by performing the governor control in consideration of the influence of the rolling of the hull.
以下、本発明の実施形態について添付図面を参照して説明する。
図1は、本発明の第1実施形態である舶用エンジンのガバナ制御システムの構成を示すブロック線図である。
Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a block diagram showing a configuration of a marine engine governor control system according to a first embodiment of the present invention.
舶用エンジンのガバナ制御システム10は、主軸11を介してプロペラ12に連結される主機13への燃料投入量を制御するものである。ガバナ制御システム10は、回転速度指令を基準入力とし、主軸11に設けられるターニングギア(図示せず)の回転を近接スイッチ等(図示せず)を用いてモニタしてエンジン実回転速度検出ブロック14においてエンジン実回転速度を検出する。検出されたエンジン実回転速度は、従来入力側へとそのままフィードバックされ、回転速度指令とエンジン実回転速度の差分がPID制御ブロック15へ入力されて主機13への燃料投入量が制御される。
The marine engine
しかし、本実施形態のガバナ制御システム10では、船体ローリング検出ブロック16において、ロールレートセンサ(図示せず)から船体の回転速度に対応する信号を取得し、この信号に基づき、変動回転速度検出ブロック17において、ローリングによる船体の回転速度、すなわち船体の対水回転速度に対応する変動回転速度が計算される。
However, in the
変動回転速度は、エンジン実回転速度検出ブロック14で検出されたエンジン実回転速度に加算され、変動回転速度により修正されたエンジン実回転速度が入力側へとフィードバックされる。すなわち、第1実施形態では、回転速度指令と対水プロペラ回転速度との差分に対応する値がPID制御ブロック15に入力され、燃料投入量のPID演算が行われる。
The variable rotational speed is added to the engine actual rotational speed detected by the engine actual rotational
以上の構成により、第1実施形態では、フィードバックされるエンジン実回転速度がローリングの回転速度により修正され、対水プロペラ回転速度を一定にするPID制御が行われることとなる。これにより、ガバナ制御装置は対水プロペラ回転速度を一定にする主機の調速制御を行い、位相遅れを防止して船体ローリングにともなう無駄な燃料投入を防止する。これにより、本実施形態のガバナ制御システムでは燃費が改善される。 With the above configuration, in the first embodiment, the feedback actual engine rotation speed is corrected by the rolling rotation speed, and PID control is performed to keep the rotation speed of the water propeller constant. As a result, the governor control device controls the speed of the main engine to keep the rotational speed of the water propeller constant, thereby preventing phase lag and preventing wasteful fuel input due to hull rolling. Thereby, in the governor control system of this embodiment, a fuel consumption is improved.
次に図2を参照して第2実施形態の舶用エンジンのガバナ制御について説明する。図2は、本発明の第2実施形態である舶用エンジンのガバナ制御システムの構成を示すブロック線図である。 Next, the governor control of the marine engine of the second embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing a configuration of a marine engine governor control system according to a second embodiment of the present invention.
第1実施形態では、変動回転速度により修正されたエンジン実回転速度を入力側へとフィードバックしたが、第2実施形態のガバナ制御システム20では、エンジン実回転速度は、従来と同様に入力側へそのままフィードバックされ、回転速度指令に変動回転速度による修正を加えている。なお、それ以外の構成については、第1実施形態と同様である。
In the first embodiment, the actual engine speed corrected by the variable engine speed is fed back to the input side. However, in the
すなわち、第2実施形態では、第1実施形態と同様に、船体ローリング検出ブロック16および変動回転速度検出ブロック17において、ロールレートセンサからの信号に基づいて船体ローリングの回転速度である変動回転速度が算出される。しかし、第2実施形態では、第1実施形態とは異なり、変動回転速度を回転速度指令から差引き、これにエンジン実回転速度検出ブロック14からのエンジン実回転速度を負帰還して、PID制御ブロック15へ入力し、主機13の燃料投入量のPID制御を行う。
That is, in the second embodiment, similarly to the first embodiment, in the hull
以上のように、第2実施形態の構成においても第1実施形態と同様の効果を得ることができる。また、第2実施形態では、船体ローリングの影響を、回転速度指令を修正する形で制御システムに取り入れているため、従来のガバナ制御装置に大きな変更を加えることなく本発明を適用することができる。 As described above, the same effects as those of the first embodiment can be obtained in the configuration of the second embodiment. Further, in the second embodiment, the effect of hull rolling is incorporated into the control system by correcting the rotational speed command, so that the present invention can be applied without greatly changing the conventional governor control device. .
なお本発明は、±1rpm程度の変動の影響が大きい低速大型機関に特に有効であり、ロングストローク、低回転の大型機関を搭載した船舶において特に有用である。 The present invention is particularly effective for a low-speed large engine that is greatly affected by fluctuations of about ± 1 rpm, and is particularly useful for a ship equipped with a long-stroke, low-rotation large engine.
また、制御方法についてはPID制御に限らず、現代制御理論、適用制御、学習制御等にも適用可能である。 Further, the control method is not limited to PID control but can be applied to modern control theory, application control, learning control, and the like.
