Adaptive Control for Marine Gas Turbine

Abstract

Gas turbines used in marine propulsion ensure increased efficiency and safety, with a very good power/weight ratio and with low maintenance and operation costs. The paper presents the control of the gas turbine so that it works in optimum operating conditions under any regime. The authors’ contribution consisted in the elaboration of control equations starting from the general equations of the gas turbine. These equations have been implemented in a digital control system that metered the fuel depending on the speed deviation. Finding the control algorithm involved determining the adjustment parameters so that the engine behaves stable at any speed. After testing the configuration on the stand, the actual testing was carried out on board the ship.
