- the ship engine control device preferably includes a memory that records a value before physical change of the physical quantity, and the correcting means includes the value of the physical quantity recorded in the memory and the value of the physical quantity estimated after the temporal change.
- the control parameter is changed based on the above.
- the physical quantity is, for example, the ship speed
- the correction means changes the control parameter in accordance with the difference in ship speed before and after aging.
- the control unit performs PID control
- the correction unit changes the P gain and / or D gain to a larger value as the ship speed difference is larger.
- the correction means changes the I gain to a smaller value as the boat speed difference increases.
- the rotational speed of the main engine is detected and fed back to the observer.
- the ship of the present invention is characterized by including the engine control device.
- the marine engine control method estimates a physical quantity that is affected by a secular change of a control target in an observer that receives an operation amount from a control unit that controls the operation of the main engine as a control target for a ship including a main engine and a hull.
- the control parameter of the control unit that controls the operation of the main engine is changed based on the value before the aging of the physical quantity and the value after the aging change.
- Controlled object 11 Control part (PID calculating part) 12 Observer 13 Memory 14 Correction Operation Unit
- FIG. 1 is a control block diagram showing a configuration of a marine engine control apparatus according to an embodiment of the present invention.
- the control object 10 includes a main machine, a propeller, a hull, and the like, and a governor command u is given from the control unit 11 to the main machine.
- the control unit 11 is a governor that performs PID control, for example, with a constant rotation speed.
- a sensor (not shown) for measuring the actual rotational speed Ne of the main machine is provided on the output shaft (not shown) of the main machine, and the actual rotational speed Ne is negatively fed back to the input side of the control unit 11. That is, the deviation between the target rotational speed No and the actual rotational speed Ne is input to the control unit 11, and the governor command u is output through the PID calculation.
- the engine control apparatus of the present embodiment includes an observer 12 in which the control target 10 is numerically modeled.
- FIG. 2 is a block diagram showing a detailed relationship between the controlled object 10 and the observer 12.
- the observer 12 receives the governor command u and uses the rotational speed N, the ship speed (vs. water speed) V, and the like as state variables.
- the observer 12 feeds back the difference between the actual rotational speed Ne and the rotational speed Nm that is the output of the simulator to the simulator, and estimates each state variable.
- A, B, C, and K in FIG. 2 are operators that operate on each variable.
- the engine control device includes a memory 13 and a correction calculation unit 14.
- the correction calculation unit 14 is a calculation unit that calculates a correction amount for correcting the control parameter of the control unit 11 in accordance with the secular change of the actual ship by using the output from the observer 12 and the data stored in the memory 13.
- the control parameter to be corrected is a PID gain
- the PID gain of the control unit 11 is updated based on the correction amount calculated by the correction calculation unit 14. Is done.
- the memory 13 records the ship speed Vmo calculated by the observer 12 at the previous control parameter update.
- the ship is sailed under the same conditions as when the ship speed Vmo was calculated, for example, with the rotation speed and fuel input amount set to the same values as the previous time, and the current ship speed Vm is set to the observer.
- the correction calculation unit 14 receives the current ship speed Vm estimated by the observer 12 and the past ship speed Vmo stored in the memory 13, and the correction amount of the control parameter of the control unit 11 based on these values. Is calculated.
- the ship speed will be slower than when it was last updated (for example, at the time of new construction) even if the sea conditions and fuel supply amount are the same. Therefore, the current ship speed Vm estimated by the observer 12 is slower than the past ship speed Vmo.
- the difference (Vmo ⁇ Vm) between the past boat speed Vmo and the current boat speed Vm is calculated as a correction amount.
- the P gain the P gain
- the D gain is set large and / or the I gain is set small. That is, when the secular change occurs, the hull resistance increases and the propeller efficiency decreases. Therefore, in order to obtain the same responsiveness as in the new construction, the gain of P and / or D is increased as the difference (Vmo ⁇ Vm) is larger. It is necessary to take big. For example, the gains of P and D are increased in proportion to the increase in (Vmo ⁇ Vm), and the I gain is decreased in inverse proportion.
- the correction calculation unit 14 also corrects the state equation in the observer 12 based on the input Vmo and Vm according to the secular change of the control target, and the simulator (numerical model) of the observer 12 performs the current control. Updated to the one corresponding to the target.

Further, in the above state equation, variables relating to the main engine and the like are omitted, but a configuration in which deterioration of the main engine valve and the like are taken into consideration can also be adopted.
- the main engine can be operated efficiently at all times. This can also reduce the sea margin and improve the fuel efficiency at the time of new construction.
- the ship speed before the secular change can be simulated with sufficient accuracy from the governor command u, this is not the past ship speed stored in the memory, but the simulated ship speed before the aging It is also possible to update the control unit and the observer by comparing the current ship speed estimated by the form observer.
