Abstract
Input-to-state stability (ISS), integral-ISS (iISS) and theirrelated notions of input/output stability and detectability havebecome a useful framework for nonlinear feedback analysis anddesign. In this paper, a new notion, that of constrainedinput-to-state stability (cISS), is presented and severalcharacterizations of cISS are obtained. cISS, unlike ISS or iISS,is not confined to forward complete systems and generalizes thesmall-signal L_inf stability. Moreover, for a class ofnonlinear systems, constrained input-to-state stabilizabilityimplies the solvability of an inverse optimal problem. The papershows that cISS is a natural concept to improve the ISS framework.
