主　　题：Rudder roll stabilization H∞/H2 Controllers Frigate 

摘      要：Roll motion of ships can be distinguished in two parts:an unavoidable part due to their natural movement while turning and an unwanted and avoidable part that is due to encounter with waves and rough seas in *** the attenuation of the unwanted part of roll motion,ways have been developed such as addition of controllable fins and changes in *** paper investigates the effectiveness of augmenting the rudder used for rejecting part of the unwanted roll,while maintaining steering and course changing *** this purpose,a controller is designed,which acts through intentional superposition of fast,compared with course change,movements of rudder,in order to attenuate the high-frequency roll effects from encountering rough *** results obtained by simulation to exogenous disturbance support the conclusion that the roll stabilization for displacement can be effective at least when displacement hull vessels are ***,robust stability and performance is verified for the proposed control scheme over the entire operating range of interest.
