Abstract: Consider the semidynamical system, , where *A* generates a -contraction semigroup and *B* is bounded. If the system is controllable then it is weakly stabilizable. If in addition the semigroup is quasi-compact and *B* is compact, the mean ergodic theorem implies that the stability is uniform and exponential.
