Locally multiobjective H/sub 2/ and H/sub /spl infin// control of large-scale interconnected marine structures

This paper presents a novel approach to design positioning and motion damping controllers by means of thruster actuations for large-scale interconnected marine structures. A locally multiobjective H/sub 2/ and H/sub /spl infin// state-feedback controller is proposed. Performance of the proposed controller is demonstrated by numerical simulations of 3 interconnected semi-submersibles.
