Stabilisation of ship roll motion via switched controllers

To control a ship motion for certain operating conditions, a particular controller may yield a most suitable performance. Therefore, a set of different types of controllers should be designed depending on various speeds, environmental and sea conditions so that appropriate controllers are selected in correspondence to these conditions. This paper addresses switched control techniques for an integrated fin and rudder roll stabilisation.
