Abstract

This paper considers the problem of fuzzy controller design for nonlinear perturbed ship steering systems. Since the model exhibits nonlinear interaction in three degrees of freedom (surge, sway and yaw) by means of main propellers aft of the ship. Therefore, this system can be replaced by Takagi-Sugeno (T-S) fuzzy model. The control purpose aimed at finding state feedback fuzzy controller such that the closed-loop system is quadratically stable and the control input energy is minimized subject to the state variance performance constraints.
