Active Control Design for Networked Offshore Platforms

This paper is concerned with networked state feedback stabilization control problem for an offshore platform. By transforming the networked closed-loop system of the offshore platform into a nonlinear delay system with time-varying delays, a new networked state feedback controller is designed to improve the control performance of the offshore platform. Simulation results demonstrate that the developed networked control scheme is effective to attenuate the oscillation amplitudes of the offshore platform significantly. In addition, in the cases of different lower bounds of network-induced delay, the maximum admissible upper bounds of the delay in the networked offshore platform are investigated.
