Abstract:

An Euler-Bernoulli beam equation with one end fixed and a tip mass at another end is considered. It is shown that the closedloop system under boundary linear feedback control is a riesz spectral system. That is, there is a sequence of generalized eigenfunctions, which forms a riest basis for the state Hilberf space. The spectrum-determined growth condition is hence established. In the meanwhile, the asymptotic expansion of the eigenvolues is derived and the exponential seability of the system is concluded.
