Title: Stability results for abstract evolution equations with intermittent time-delay feedback,
Abstract: We consider abstract evolution equations with on-off time delay feedback.
Without the time delay term, the model is described by an exponentially stable
semigroup. We show that, under appropriate conditions involving the delay term,
the system remains asymptotically stable. Under additional assumptions
exponential stability results are also obtained. Concrete examples illustrating
the abstract results are finally given.
