Title:
MARINE ENGINE CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2012/032878
Kind Code:
A1
Abstract:
The actual number of rotations (NE) of a main shaft (14) connected to a main engine (12) is detected. A PID operation is performed on the difference between a number-of-rotations command (NO) and an actual number of rotations (NE) in a control operation unit (17). A governor command obtained by the PID operation is outputted to a governor (13) to control the fuel quantity to be supplied to the main engine (12). Further, the governor command and the actual number of rotations (NE) are inputted to an observer (18) of a control subject (S) to estimate the propeller inflow velocity variation. In an operation unit (19), the number-of-rotations command (NO) is corrected by multiplying the propeller inflow velocity variation by a predetermined gain and adding the result to the number-of-rotations command (NO).
