Abstract

A method for controller design and switching controller without bump effect has been proposed for a marine propulsion system with diesel engine used as propeller prime-mover. Due to different regimens operation of ship propulsion, it is common practice to design more than one linear controller, each at a different operating point, and to switch between them; which enables the system to be controlled satisfactorily within the whole of its operating range. Each design consists of a feedback H-controller (FB-HC) and an associated bump-less transfer H-controller (BLT-HC). The method is implemented in an auto-tuning procedure and satisfactory results are obtained using real time hardware in the loop simulations (HILS).
