Description

本発明は、ターボ過給機を備えたエンジンのガバナ制御装置に関する。   The present invention relates to a governor control device for an engine equipped with a turbocharger.

例えば舶用エンジンの制御では、設定された目標回転数と実回転数の差がなくなるようにガバナ制御が行われる。しかし、ターボ過給機を備えた舶用エンジンにおいて、荒天時の波浪による短い周期の負荷変動に追従して燃料投入量を増減させると、負荷増大時に空気過剰率が低下して燃費の悪化を招く。このような問題に対して、波浪による負荷の増大時に、燃料投入量を一定に保持する構成が提案されている（特許文献１）。   For example, in marine engine control, governor control is performed so that the difference between the set target rotational speed and the actual rotational speed is eliminated. However, in a marine engine equipped with a turbocharger, if the amount of fuel input is increased or decreased following a short-period load fluctuation due to stormy weather, the excess air ratio decreases when the load increases, leading to deterioration of fuel consumption. . In response to such a problem, a configuration has been proposed in which the amount of fuel input is kept constant when the load due to waves increases (Patent Document 1).

特開平４−３１６４５号公報Japanese Patent Laid-Open No. 4-31645

しかし、特許文献１の構成では、負荷変動に対して燃料投入量を一定に保持しているため、必ずしも十分適正なガバナ制御が行われているとは言えず、燃費の改善も十分とは言えない。また、特許文献１は、波浪による負荷変動における空気過剰率の低下には対応しているが、船舶の加速を目的として目標回転数が上げられる場合に発生する空気過剰率低下の問題に対応することはできない。   However, in the configuration of Patent Document 1, since the fuel input amount is kept constant with respect to the load fluctuation, it cannot be said that the adequate governor control is necessarily performed, and the fuel consumption can be improved sufficiently. Absent. Moreover, although patent document 1 respond | corresponds to the fall of the excess air ratio in the load fluctuation by a wave, it respond | corresponds to the problem of the excess air ratio fall generate | occur | produced when the target rotation speed is raised for the purpose of the acceleration of a ship. It is not possible.

本発明は、ターボ過給機を備えたエンジンにおいて、ターボラグを考慮してより精密な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 fuel efficiency by performing more precise governor control in consideration of turbo lag in an engine equipped with a turbocharger.

本発明のガバナ制御装置は、ターボ過給機を備えるエンジンのガバナ制御装置であって、回転数指令とエンジン実回転数の間の偏差に基づきガバナ指令を演算して出力する制御手段と、エンジン実回転数が回転数指令よりも小さいときに、所定期間に渡って上記演算に基づくガバナ指令の出力を停止し、その間ガバナ指令を漸次増大して出力する規制手段とを備えたことを特徴としている。   A governor control device according to the present invention is a governor control device for an engine having a turbocharger, and calculates and outputs a governor command based on a deviation between a rotational speed command and an actual engine rotational speed, and an engine And a regulation means for stopping the output of the governor command based on the above calculation over a predetermined period when the actual rotational speed is smaller than the rotational speed command, and gradually increasing and outputting the governor command during that period. Yes.

また本発明のガバナ制御方法は、ターボ過給機を備えるエンジンのガバナ制御方法であって、回転数指令とエンジン実回転数の間の偏差に基づきガバナ指令を演算して出力し、エンジン実回転数が回転数指令よりも小さいときに、所定期間に渡って上記演算に基づくガバナ指令を停止し、その間ガバナ指令を漸次増大して出力することを特徴としている。   The governor control method of the present invention is a governor control method for an engine equipped with a turbocharger, which calculates and outputs a governor command based on a deviation between the rotational speed command and the actual engine rotational speed, When the number is smaller than the rotational speed command, the governor command based on the above calculation is stopped for a predetermined period, and the governor command is gradually increased and output during that period.

所定期間はターボラグ期間に相当することが好ましい。上記演算に基づくガバナ指令の出力が停止されたときに、ガバナ指令が実質的に連続的に増大されて出力されることが好ましく、ガバナ指令の増大量は、例えば現ガバナ指令の１％〜１０％に制限される。また、本発明のガバナ制御装置、制御方法は、特に船舶用の主機の制御に好適である。   It is preferable that the predetermined period corresponds to a turbo lag period. When the output of the governor command based on the above calculation is stopped, the governor command is preferably increased and output substantially continuously. The increase amount of the governor command is, for example, 1% to 10% of the current governor command. %. The governor control device and control method of the present invention are particularly suitable for controlling a main engine for a ship.

また、本発明の船舶は、船体と、船体に搭載されるエンジンと、エンジンへの過給を行うターボ過給機と、エンジンへの燃料投入量を制御するガバナ制御装置とを備え、ガバナ制御装置が、回転数指令とエンジン実回転数の間の偏差に基づきガバナ指令を演算して出力する制御手段と、エンジン実回転数が回転数指令よりも小さいときに、所定期間に渡って演算に基づくガバナ指令の出力を停止し、その間ガバナ指令を漸次増大して出力する規制手段とを備えたことを特徴としている。   The ship of the present invention includes a hull, an engine mounted on the hull, a turbocharger that supercharges the engine, and a governor control device that controls the amount of fuel input to the engine.

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、本発明の一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 an embodiment of the present invention.

本実施形態のガバナ制御システム１０は、ターボ過給機１３Ｔを備え、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、回転数指令を入力とし、主軸１１に設けられたターニングギア（図示せず）の回転をモニタして実回転数検出ブロック１４においてエンジン実回転数を検出して入力側へとフィードバックする。すなわち、回転数指令とエンジン実回転数の偏差がＰＩＤ演算部１５へと入力される。   The governor control system 10 of the present embodiment includes a turbocharger 13T and controls the amount of fuel input to the main machine 13 connected to the propeller 12 via the main shaft 11. The governor control system 10 receives the rotational speed command, monitors the rotation of a turning gear (not shown) provided on the main shaft 11, detects the actual rotational speed of the engine at the actual rotational speed detection block 14, and moves to the input side. Feedback. That is, the deviation between the rotational speed command and the actual engine rotational speed is input to the PID calculation unit 15.

ＰＩＤ演算部１５に入力された偏差には、それぞれ比例動作Ｐ、積分動作Ｉ、微分動作Ｄが施され、その出力はスイッチ１６に入力される。また、スイッチ１６には、ＰＩＤ制御規制部１７からの出力が入力される。すなわち、スイッチ１６は、ＰＩＤ演算部１５からの出力と、ＰＩＤ制御規制部１７からの出力を選択的に切り替えて、ガバナ指令として主機１３への燃料供給を行う燃料供給装置１８へ供給する。なお、ガバナ指令は、例えばプランジャ容量を制御するレバー位置（ガバナポジション）等に対応する。   The deviation input to the PID calculation unit 15 is subjected to a proportional operation P, an integration operation I, and a differentiation operation D, and the output is input to the switch 16. The switch 16 receives an output from the PID control restriction unit 17. That is, the switch 16 selectively switches the output from the PID calculation unit 15 and the output from the PID control regulation unit 17 and supplies the fuel supply device 18 that supplies fuel to the main engine 13 as a governor command. The governor command corresponds to, for example, a lever position (governor position) for controlling the plunger capacity.

ＰＩＤ制御規制部１７は、スイッチ１６からの出力である現在のガバナ指令を入力とし、これに入力の例えば１％を加算して出力する。また、スイッチ１６の切り替えは、実回転数検出ブロック１４からのエンジン実回転数（入力Ａ）と回転数指令（入力Ｂ）の比較を行う比較部１９によって行われる。すなわち、比較部１９は、実回転数が回転数指令よりも小さいときに例えばＨｉ信号を出力して、スイッチ１６はＰＩＤ制御規制部１７からの出力を選択し、それ以外（エンジン実回転数が回転数指令以上）のときに比較部１９は、例えばＬｏ信号を出力して、スイッチ１６はＰＩＤ演算部１５からの出力を選択する。   The PID control restriction unit 17 receives the current governor command, which is an output from the switch 16, and adds, for example, 1% of the input to the output. The switch 16 is switched by a comparison unit 19 that compares the actual engine speed (input A) and the engine speed command (input B) from the actual engine speed detection block 14. That is, the comparison unit 19 outputs, for example, a Hi signal when the actual rotational speed is smaller than the rotational speed command, the switch 16 selects the output from the PID control restricting unit 17, and otherwise (the actual engine rotational speed is For example, the comparison unit 19 outputs a Lo signal, and the switch 16 selects the output from the PID calculation unit 15.

また、比較部１９の出力は、ＰＩＤ演算部１５のＩ動作における積分値をリセットするためのリセット信号にも利用される。Ｉ動作のリセットは、ガバナ指令をＰＩＤ制御規制部１７からの出力からＰＩＤ演算部１５からの出力に切り替える際に行われるもので、上のＨｉ、Ｌｏ信号の例では、ＨｉからＬｏに切り替えられたときに、積分値は、現在のガバナ指令値にリセットされる。   The output of the comparison unit 19 is also used as a reset signal for resetting the integral value in the I operation of the PID calculation unit 15. The resetting of the I operation is performed when the governor command is switched from the output from the PID control restricting unit 17 to the output from the PID calculating unit 15, and in the example of the above Hi and Lo signals, it is switched from Hi to Lo. The integrated value is reset to the current governor command value.

すなわち、本実施形態のガバナ制御システムでは、実回転数が回転数指令よりも小さいときには、ＰＩＤ制御規制部１７からの出力がガバナ指令として用いられ、エンジン実回転数が回転数指令以上のときには、ＰＩＤ演算部１５からの出力がガバナ指令として用いられる。   That is, in the governor control system of the present embodiment, when the actual rotational speed is smaller than the rotational speed command, the output from the PID control restriction unit 17 is used as the governor command, and when the actual engine rotational speed is equal to or higher than the rotational speed command, The output from the PID calculation unit 15 is used as a governor command.

図２、図３に、ガバナ制御システム１０におけるガバナ指令の時系列変化をそれぞれ示す。なお、図２、３において、横軸は時間、縦軸はガバナ指令値を表す。また、各図において、実線は、ＰＩＤ演算部１５の出力、破線はスイッチ１６の出力であるガバナ指令の値を示す。   2 and 3 show time series changes of the governor command in the governor control system 10, respectively. 2 and 3, the horizontal axis represents time, and the vertical axis represents the governor command value. Moreover, in each figure, a continuous line shows the value of the governor command which is an output of the PID calculating part 15, and a broken line shows the output of the switch 16.

図２は、実回転数が回転数指令よりも小さくなったとき、すなわち負荷が増大し回転数が低下する場合や、回転数指令が上げられた場合（例えば船を加速させる場合）に対応する。図２において、時刻ｔ０に負荷が増大し回転数が低下する、あるいは加速の指令が与えられると、スイッチ１６から燃料供給装置１８へのガバナ指令は、ＰＩＤ演算部１５の出力からＰＩＤ制御規制部１７の出力に切り替えられる。これにより、ガバナ指令は、破線に示されるように期間Ｔに渡って漸次増大し（１％の傾きで）、期間Ｔが経過すると、エンジン実回転数が回転数指令に達し、スイッチ１６の出力は、Ｉ動作を現ガバナ指令値にリセットするとともに、ＰＩＤ演算部１５からの出力に選択を切り替える。 FIG. 2 corresponds to the case where the actual rotational speed becomes smaller than the rotational speed command, that is, when the load increases and the rotational speed decreases, or when the rotational speed command is increased (for example, when the ship is accelerated). . In FIG. 2, when the load increases at time t 0 and the rotational speed decreases or an acceleration command is given, the governor command from the switch 16 to the fuel supply device 18 is changed from the output of the PID calculation unit 15 to the PID control regulation. The output is switched to the output of the unit 17. As a result, the governor command gradually increases over a period T (inclination of 1%) as indicated by a broken line. When the period T elapses, the actual engine speed reaches the speed command, and the output of the switch 16 Resets the I operation to the current governor command value and switches the selection to the output from the PID calculation unit 15.

一方、図３は、エンジン実回転数が回転数指令以上となったとき、すなわち負荷が低減し回転数が増大する場合や、回転数指令が下げられた場合（例えば船を減速させる場合）に対応する。図３において、時刻ｔ１に負荷が低減し回転数が増大する、あるいは減速の指令が与えられると、スイッチ１６から燃料供給装置１８へのガバナ指令は、ＰＩＤ演算部１５の出力に維持される。これにより、ガバナ指令は、通常のＰＩＤ制御時の実線と同様に、破線に示されるように変化する。 On the other hand, FIG. 3 shows a case where the actual engine speed becomes equal to or higher than the engine speed command, that is, when the load decreases and the engine speed increases, or when the engine speed command is lowered (for example, when the ship is decelerated). Correspond. In FIG. 3, when a load is reduced and the rotational speed is increased or a deceleration command is given at time t 1 , the governor command from the switch 16 to the fuel supply device 18 is maintained at the output of the PID calculation unit 15. . As a result, the governor command changes as indicated by the broken line, similarly to the solid line during normal PID control.

期間Ｔは、ターボ過給機１３Ｔのターボラグに相当する所定の期間に設定され、これに合わせて、上記増加率は設定される。すなわち、本実施形態では、現在のガバナ指令を漸次１％ずつ増加させる構成としているが、ＰＩＤ制御規制部１７の出力は、略ターボラグ相当する期間にＰＩＤ制御規制部１７からの出力に切り替えられるように漸次増大する構成であればよく、増加率は例えば１％〜１０％程度である。また、増加方法も本実施形態の構成に限定されるものではない。   The period T is set to a predetermined period corresponding to the turbo lag of the turbocharger 13T, and the increase rate is set accordingly. That is, in the present embodiment, the current governor command is gradually increased by 1%, but the output of the PID control restriction unit 17 is switched to the output from the PID control restriction unit 17 in a period substantially corresponding to a turbo lag. The rate of increase is, for example, about 1% to 10%. Further, the increasing method is not limited to the configuration of the present embodiment.

以上のように、本実施形態によれば、ターボラグが存在しても、荒天時などの負荷増大時や加速時における燃料投入量の急激な増大を抑制し、空気過剰率の低下を防止することができ、これにより燃費を改善することができる。また、負荷低減時や減速時には、より迅速に燃料投入量を減らして、エンジンの過回転を防止できる。更に本実施形態では、ＰＩＤ制御規制時にもガバナ指令は漸次増加しているので、掃気圧の増大に対応して燃料投入量の増大を図ることができ、より適正なガバナ制御を実現できる。   As described above, according to the present embodiment, even when a turbo lag is present, it is possible to suppress a rapid increase in the amount of fuel input during an increase in load such as during stormy weather or during acceleration, and to prevent a decrease in the excess air ratio. This can improve fuel efficiency. In addition, when the load is reduced or decelerated, the amount of fuel input can be reduced more quickly to prevent engine overspeed. Further, in this embodiment, since the governor command is gradually increased even when the PID control is restricted, it is possible to increase the amount of fuel input corresponding to the increase in the scavenging air pressure, thereby realizing more appropriate governor control.

なお、本発明は、特に大型の舶用ディーゼルエンジンにおいて特に有効であるが、例えば陸用の大型エンジンに適用することも可能である。   The present invention is particularly effective for a large marine diesel engine, but can also be applied to, for example, a large land engine.

更に、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。   Furthermore, the control method is not limited to PID control, but can be applied to modern control theory, application control, learning control, and the like.
