Abstract
A method for maintaining position and/or heading of a marine vessel in a body of water includes accepting a command to maintain the vessel at an initial selected position and/or heading, and utilizing position/heading feedback control to determine initial steering angles, gear positions, and engine speeds for the vessel's propulsion devices that cause the propulsion devices to produce thrust that counteracts a net external force and moment on the vessel and maintains the vessel at the initial selected position/heading. The method also includes propelling the vessel to a new selected position/heading, and accepting a command to maintain the vessel at the new selected position/heading. The method next includes utilizing information related to one of the position/heading feedback control and the propulsion devices' thrust to predict control parameters required to maintain the vessel at the new selected position/heading, and controlling the propulsion device according to the predicted control parameters.
