ISS and integral ISS coincide for linear systems with bounded inputs
Abstract
We show that input-to-state stability (ISS) and integral input-to-state stability (integral ISS) with respect to the space of essentially bounded functions are equivalent properties for linear systems. The proof combines recent results on Orlicz-admissibility and a duality result due to the authors. As a direct consequence, we show that, given an L∞-admissible control operator, the mild solutions of the linear system are continuous, resolving a question by G.\ Weiss.
