| Abstract: | This paper deals with the problem of integral input-to-state stability (iISS) for switched nonlinear systems
with unstable subsystems. A Lyapunov-like function with indefinite derivative is introduced to derive the iISS of switched
nonlinear systems, which generalizes the classic Lyapunov function with positive definite derivative. Two cases are considered.
A switched nonlinear system is iISS if all subsystems are iISS. Moreover, if some of subsystems are not iISS, the iISS
property is shown for the switched nonlinear systems. An illustrative example is presented to demonstrate the effectiveness
of the main results. |
