Abstract

A control design method based on the inverse LMI control algorithm is proposed and applied to a position keeping system of a floating vehicle. The LMI control algorithm is developed to cope with the step response command of the controller. Also, the inverse LMI control algorithm is newly created for a user (designer) friendly style. The inverse LMI control design method is applied to the dynamic positioning system design of an offshore platform. A LPV (linear parameter varying) model for the offshore platform is derived by its nonlinear model, and the inverse LMI control design is successfully conducted. Effectiveness of the control design method is confirmed by numerical simulation. The method can cope with the nonlinear and robust control problems, and get the control output determined by the control constraint command easily
