Problems solved by technology

This independent control method has obvious limitations because it does not directly consider the significant impact of the speed on the rudder effect of the ship. In most working conditions, the comprehensive optimal control of the ship system has not been realized.

Embodiment Construction

[0013] The present invention is described in further detail below in conjunction with accompanying drawing:

[0014] The ship steering and main propulsion joint control method of the present invention, according to the ship driver's rudder order and speed vehicle order, realizes comprehensive coordination of factors such as ship maneuverability, main engine operating characteristics, ship loading, marine environment disturbance, navigation safety, and economic navigation. Integrated joint control of ship motion (autopilot) and main engine operation (fuel delivery).

[0015] For ships with large rudder angles or navigating in shallow and narrow waterways, the specific steps for adopting comprehensive optimization and joint control of the ship's diesel engine and autopilot are as follows:

[0016] (1) In the main engine remote control system, set up the program of the optimized performance index function including the main engine load, ship speed, rudder angle, bow turning angul...

Abstract

The invention discloses a ship manoeuvring and main propulsion combination control method and a simulation system thereof, and relates to the technical field of ship control. According to course steering order and speed engine order of a ship driver, the control method achieves integrative combined control of factors such as general coordinated ship maneuverability, host performance characteristic, ship loading, marine environment disturbance, safe navigation, economic navigation and the like to motion of the ship and running of a propulsion host; and the simulation system verifies validity of the ship manoeuvring and main propulsion combination control method. The control method and the simulation system have the advantages of improving integral economical efficiency and maneuverability of a ship system, improving control effect on motion of the ship, facilitating safe navigation of the ship, preventing a diesel host from overloading, and improving reliability and economical efficiency of a power device.

Description

technical field [0001] The invention relates to the technical field of ship control, in particular to a joint control method for ship maneuvering and main propulsion and a simulation system thereof. Background technique [0002] During the voyage of the ship, due to the change of course, the interference of wind, wave and current in the ocean environment, the resistance of the ship and the torque of the propeller will change, and the power of the main engine of the ship is limited, and it is limited by conditions such as thermal load and mechanical load. It is difficult to ensure that the main engine The rotational speed is stable and the vessel speed is constant. The speed of the ship's main engine directly affects the ship's speed, and the change of the ship's speed and draft affects the maneuverability of the ship, that is, the ship's motion state is also closely related to the main engine's speed and operating conditions, so there is a strong coupling relationship betwee...
