ON A DYNAMIC POSITIONING SYSTEM FOR SHIP WITH ILQ OPTIMAL SERVO THEORY

Linear quadratic (LQ) optimal regulator theory is often applied to the design and control system of a dynamic positioning system for ships. However, it is very difficult to select suitable weighting matrices in the performance index at the design stage. From a viewpoint of practical use, inverse linear quadratic (ILQ) optimal servo theory has recently been proposed which makes the design of the control system easier in comparison with LQ optimal regulator theory. In this paper, the ILQ optimal servo theory is applied to the control system of DPS for ships and the performance of the control system in comparison with the control system designed using LQ optimal regulator theory is examined.
