Abstract
Generally control systems of DPS to keep position of offshore platforms are designed mainly based on PID control theory. However, the motions of offshore platform complicate with the component of surge, sway and yaw motions. Then it will be of the most importance taking account of those components in the control systems. Furthermore, it is known that the control forces generated by thruster decrease under the influence of forward speed. Additionally, the thrusters produce an inherent time lag between the actuation and the final response that thrusters produce required control forces. We applied the linear quadratic (LQ) optimal regulator control theory to the Dynamic Positioning System for offshore platform in order to take the motion of surge, sway and yaw into account. We also took the time lag in the thruster response into account to evaluate the performance of the control system of DPS.
