Sensitivity Optimisation of a Main Marine Diesel Engine Electronic Speed Governor

Electronic speed governors have become widespread on marine diesel engines. In comparison with hydromechanical ones, they an additional setting parameter – input signal sensitivity. This allows changing the response of to high-frequency disturbances. camshaft engines, such disturbances are generated when cams run over fuels pump push rods, while in ME (MAN Energy Solutions) or RT-flex (Wärtsilä) engines result from use inductive sensors a serrated tape shaft for measurement. If engine is used as main vessels, governor’s sensitivity additionally vary propeller resistance moment fluctuations sea waves conditions. practice value electronic selected intuitively. As result, adjustment doesn’t provide satisfactory stability modes at change The study aims develop methodology adjusting considering stochasticity load state. was carried out using systems automatic control model, which based assumption relatively small deviations rotation and parameters Considering character magnitude conditions depend many variables external (waves levels, course vessel relation wind-wave conditions, wind gusts, vessel’s loading condition, given vessel), any set appears be optimum only particular case movement scientific novelty defined by fact that recommendations choice governor determined increased accuracy, validity recommendations. practical significance research consist increase various
