This paper makes a research about the vibration damping of a flexible riser system. The partial-ordinary differential equations can be used to describe the riser system. Through the fusion of the boundary control and backstepping technique, a control strategy is proposed for suppressing riser's vibration and globally stabilizing the riser system at its equilibrium position, an auxiliary system is...
This study addresses control design for an axially moving belt system including high acceleration/deceleration (H-A/D). The corresponding dynamics is described by the partial-ordinary differential equations. When some of the system states can not be accurately measured, output feedback boundary control is proposed by utilizing high-gain observers for estimating unmeasurable system states. The disturbance...
In this paper, the modeling and vibration control problem of an axially moving belt with high acceleration/deceleration under unknown disturbances are addressed. The dynamic model of the belt system is represented by a nonhomogeneous hyperbolic partial differential equation and two ordinary differential equations. Boundary control with disturbance adaption is developed to stabilize the transverse...
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...
