Exponential stability of Timoshenko beam system with delay terms in boundary feedbacks

Zhong-Jie HanGen-Qi Xu — 2011

ESAIM: Control, Optimisation and Calculus of Variations


In this paper, the stability of a Timoshenko beam with time delays in the boundary input is studied. The system is fixed at the left end, and at the other end there are feedback controllers, in which time delays exist. We prove that this closed loop system is well-posed. By the complete spectral analysis, we show that there is a sequence of eigenvectors and generalized eigenvectors of the system operator that forms a Riesz basis for the state Hilbert space. Hence the system satisfies the spectrum...
