Quasi-passivity and feedback quasi-passification for switched nonlinear systems

This paper studies the issues of quasi-passivity, feedback quasi-passification for a class of switched nonlinear system using multiple storage functions. A quasi-passivity concept for a switched nonlinear system is proposed. Firstly, a state-dependent switching law is designed to render a switched nonlinear system quasi-passive. Secondly, quasi-passification is achieved by the design of a state-dependent switching law and state feedback controllers for switched nonlinear systems. Finally, a numerical example is presented to illustrate the effectiveness of the proposed approach.
