Resumo

YAMAMOTO, M.  e  MOROOKA, C. K.. Dynamic positioning system of semi-submersible platform using fuzzy control. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2005, vol.27, n.4, pp.449-455. ISSN 1678-5878.  http://dx.doi.org/10.1590/S1678-58782005000400014.

The purpose of this paper is the study of fuzzy control applied to a Dynamic Positioning System (DPS) of semi-submersible platforms. A numerical simulator program in time domain was coded using mathematical models of the floating platform dynamics and the external forces (wind, current, wave and thruster) that act on the platform. Subsequently, a fuzzy controller applied to DPS was developed. The Fuzzy controller and the Proportional-Integral-Derivative (PID) controller were then subjected to the same environmental conditions in order to compare their performance.

Palavras-chave : Offshore petroleum; ocean waves; floating drilling platform; and dynamic positioning system.
