RUDDER ROLL STABILIZATION - CONTROLLER DESIGN AND EXPERIMENTAL RESULTS

TL;DRAbstract

This paper gives a survey of the design of a controller for rudder roll stabilisation. Besides a review of earlier results, which were reported at the Seventh Ship Control Systems Symposium in 1984, the paper focuses on some of the recent results of the project. A new mathematical model which describes the rudder-to-roll transfer as well as the rudder-to-yaw transfer has been developed and adaptive properties have been added to the controller. In its present form the controller adapts itself to changing sea states and to the controller. In its present form the controller adapts itself to changing sea automatic adjustment of the weighting factors of a quadratic criterion, followed by on-line optimisation of the controller parameters. The adjustment of the weighting factors is determined by some simple rules and a knowledge base. The new algorithms have been tested during several simulation experiments and partly during full-scale trials. At present the results of the research have been
