Abstract

In this paper we consider the control problem of Dynamic Positioning Systems for Ships (DPSS). It interests as a case which study in nonlinear controller design because the model exhibits nonlinear interaction in three degrees of freedom (surge, sway, and yaw) by means of main propellers aft of the ship. The DPSS system considered in this paper is modeled by a Takagi-Sugeno (T-S) type fuzzy model. By using linear feedback controller design technology, we design a nonlinear fuzzy controller for the T-S type fuzzy-based DPSS. Finally, simulation results show the utility of the present fuzzy control methodology.
