Passivity and feedback equivalence of switched nonlinear systems with storage-like functions

This paper addresses the issues of passivity and feedback equivalence for switched nonlinear systems via multiple storage functions. The concept of storage-like functions for switched systems is presented. A sufficient condition for passivity of the switched nonlinear systems is given via multiple storage functions under some switching signal. Then, the result is extended to find conditions under which the switched system is feedback equivalent to a passive switched system.
