The present paper addresses a coupled system of waves with indirect control. First, using Semigroup Theory we prove the existence of solution applying the Lumer-Phillips theorem. We show the exponential decay of the solution using Nakao’s method. Computational experiments are conducted in the one-dimensional case in order to show that the dissipative energy properties are present. To obtain the time behavior of the energy of system, we resolve two numerical tests. Finally, in both tests, we conclude that the system, for one-dimensional case, is dissipative with exponential stability.
