This paper investigates vibration control problem of a flexible marine riser coupled with the internal fluid dynamics. By applying Lyapunov's direct method, boundary control technique and high-gain observers, an output feedback boundary control is proposed to suppress the vibration of the riser system. With the proposed control, the control spillover is avoided and the stability of the closed-loop...
In this paper, output feedback boundary control of a flexible marine riser coupled with the internal fluid dynamics is investigated. By merging Lyapunov's direct method, boundary control technique and high-gain observers, an output feedback boundary control with disturbance observer is proposed to suppress the riser's vibration and deal with the effects of the external environment disturbance. The...
This paper revisits the multivariable MRAC problem, by studying adaptive state feedback control for output tracking of multi-input and multi-output (MIMO) systems. With such a control scheme, the plant-model matching condition is much less restrictive than those for state tracking, while the controller enjoys a simpler structure than that of an output feedback design with the guarantee of the asymptotic...
