This paper is concerned with network-based control for an offshore steel jacket platform subject to nonlinear wave-induced force. A network-based dynamic model of the offshore platform is presented and a network-based state feedback control scheme is developed to reduce the internal oscillations of the offshore platform. Then the effect of a network-induced delay on the control performance of the offshore platform is investigated. It is found through simulation results that (i) the network-based state feedback controller is of a smaller gain in the sense of Euclidean norm than the state feedback controller without network setting, which means the network-based state feedback controller requires less control force; and (ii) the network-induced delay is of the positive effect on state feedback control of the offshore platform.
