In this subsection,we develop equations of the transverse motion of the riser,and of the hydraulic system.
These equations will be used for the boundary control design in the next section.In developing these
equations,we make the following assumption:
Assumption 1.(1) The riser can be modeled as a beam rather than a shell since the diameter-to-length of the
riser is small,i.e.we consider the riser as a slender structure.
(2) Plane sections remain plane after deformation,i.e.warping is neglected.
(3) The riser is locally stiff,i.e.cross sections do not deform and Poisson effect is neglected.
(4) The riser material is homogeneous,isotropic and linearly elastic,i.e.it obeys Hookes’s law.
(5) Torsional and distributed moments induced by environmental disturbances are neglected.
(6) The riser deforms in one vertical plane,and its axial motion is ignored.
