Abstract
This paper has two objectives. First, necessary and sufficient conditi ons are given to characterize the uniform exponential stability of a s equence of c0-semigroups T(n)(t) on Hilbert space H(n). Secondly, appr oximation in control of a one-dimensional thermoelastic system, subjec t to Dirichlet-Dirichlet as well as Dirichlet-Neumann boundary conditi ons, is considered. The uniform exponential stability and strong conve rgence of corresponding semigroups associated with approximate scheme are proved. Numerical experimental results are also presented.
