Abstract

Dynamic Positioning System (DPS) is used in FPSO to keep her positional stability in deep waters where the use of conventional mooring systems is generally not available. The Inverse Linear Quadratic (ILQ) optimal servo theory is applied to design control system of DPS in this paper. In this method, it is able to construct a control system which has no interaction among control variables and express an optimal feedback gain in terms of the system matrices and design parameters. Numerical simulations were carried out for some time constants which influence on the performance of the control system.
