| Abstract: | In this paper we characterize the output feedback stabilization of some coupled systems with and without delay. The proof of the main result uses the method introduced in Haraux (Port. Math., 46:245–258, 1989), which consists of reducing the exponential decay of the closed loop system to an observability inequality of its corresponding conservative adjoint system. |
