Abstract
The perturbations in parameters or structure of the ship are important for RRD. H∞ control is useful in the design of RRD controllers when this kind of model uncertainty exists. The design method of a parallel RRD controller is discussed. The course keeping controller with a wave observer and the roll damping controller are designed by mixed sensitivity approach to deal with the perturbations. The seaway simulation results show that the rudder motion is very small when course keeping is in operation only, and the effectiveness of RRD is satisfactory when it is active.
