This paper is concerned with network-based H∞ control for an offshore steel jacket platform subject to nonlinear wave-induced force and external disturbance. A network-based dynamic model of the offshore platform with an active tuned mass damper mechanism is presented, and a network-based H∞ control scheme is presented to attenuate the vibration of the offshore platform. The effects of the network-induced...
This paper is concerned with network-based control for an offshore steel jacket platform with an active tuned mass damper mechanism. A network-based dynamic model of the offshore platform is presented first. Then, a network-based state feedback control scheme is developed. Based on a proposed Lyapunov-Krasovskii functional, a delay-dependent stability criterion for the offshore platform system is...
This paper is concerned with active control for an offshore steel jacket platform subjected to wave-induced force and parameter perturbations. An uncertain dynamic model for the offshore platform is first established, where uncertainties not only on the natural frequency and the damping ratio of both the offshore platform and the active tuned mass damper (TMD) but also on the damping and stiffness...
This paper is concerned with robust sliding mode H∞ control using time-varying delayed states for an offshore steel jacket platforms subject to self-excited nonlinear wave force, external disturbance and parametric uncertainties. By intension-ally introducing a time-varying delay into the control channel, a delayed robust sliding mode H∞ controller is designed to reduce the internal oscillations of...
