Title:
MARINE ENGINE CONTROL DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2011/122375
Kind Code:
A1
Abstract:
An observer (12) which simulates subjects to be monitored (10) including a hull, a main engine, and a propeller, is provided. A governor command (u) which is issued by a control section (11) and serves to control the main engine constitutes an input into the observer (12). An actual rotational speed (Ne) of the main engine is fed back to the observer (12). A pre-aging-degradation ship speed (Vmo) estimated by the observer (12) is saved in a memory (13). Control parameters are corrected on the basis of the difference between the pre-aging-degradation ship speed (Vmo) and a ship speed (Vm) estimated by the observer (12) after aging degradation.
