Abstract: | A nonlinear hinged extensible elastic body equation with strong structural damping and Balakrishnan-Taylor damping of full
exponent is studied as a general model for large space structures of higher dimensions. In this paper, the absorbing sets
and flat inertial manifold are obtained for this nonlinear body equation. The control spillover problem associated with the
stabilization of this equation is resolved by constructing a linear finite dimensional feedback, control based on the existence
of inertial manifolds of the uncontrolled equation. Moreover, the results obtained are robust with respect to the uncertainty
in structural parameters.
