In this paper, a new adaptive fuzzy controller is proposed for the dynamic positioning system of vessels with unknown time-varying dynamic model parameters and environmental disturbances. This controller comprises of an adaptive fuzzy logic and the dynamic surface control (DSC) technique. The adaptive fuzzy system is used to estimate the uncertainties induced by unknown dynamic model parameters and...
For floating production storage and offloading (FPSO) vessels, a positioning controller is necessary because only a mooring system alone cannot always keep the ship within a predefined region. This paper develops a new adaptive backstepping controller based on structural reliability index to deal with the model uncertainties of the FPSO vessel. Model uncertainties can be estimated by the adaptive...
