Abstract: Abstract:With the development of fuzzy approach, the stability analysis and synthesis of nonlinear Dynamic Positioning Systems for Ship (DPSS) with external disturbances is investigated in this paper. Through applying the Takagi-Sugeno (T-S) fuzzy model approach, the nonlinearities of DPSS can be described by fuzzy set and apply linear controller design method to design fuzzy controller. According to disturbed environment of ocean, the strictly input passive theory is used for attenuating the external disturbance effect on the system in this paper. By the calculation technique, the Linear Matrix Inequality (LMI) approach (convex optimization algorithm) is used to find the feasible solutions with the developed stability condition of this paper. Form the simulation results, the disturbed DPSS can be stabilized and achieved strictly input passive via designed fuzzy controller.
