Title:
ELECTRIC PROPULSION CONTROL SYSTEM FOR VESSEL
Document Type and Number:
WIPO Patent Application WO/2024/043704
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an electric propulsion control system that has improved acceleration/deceleration and control performance and that can be linked to an autonomous navigation system. The electric propulsion control system for a vessel, according to one embodiment of the present invention, may comprise: an acceleration/deceleration control unit which receives a speed command so as to control acceleration on the basis of the output change rate of an engine of a vessel, and which limits a torque command value according to the speed command within a safety driving region so as control deceleration; and a regenerative energy control unit for estimating the generation amount of regenerative energy on the basis of the propeller speed of the vessel and a torque command generated by means of the acceleration/deceleration control unit, and controlling torque limitation of the acceleration/deceleration control unit such that the estimated generation amount of regenerative energy is less than or equal to the current load amount.
