The H∞ analysis problem is studied for switched nonlinear systems based on the output strict passivity property.
By assuming that each subsystem satisfies the output strict passivity inequality when it is active, which is not satisfied for the
whole time domain, the switching law can be designed to achieve the H∞ performance index by using the multiple Lyapunov
function method. Finally, a numerical example is given to illustrate the effectiveness of the main result.
