Stability analysis for the systems with feedback norm constraint uncertainties

This paper considers the problem of L-p stability checking for a feedback uncertain system which consists of a linear plant in its forward loop and non-linear uncertain dynamics in its feedback loop. It is supposed that the non-linear part of the system is of dynamic uncertainties characterized by a certain set of constraints. The concepts used here are the well-posedness of the feedback system and the norm constraint for the feedback uncertainties, leading to a sufficient condition for robust stability. The result is illustrated to be efficient through an example.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000169282900007&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Automation & Control SystemsSCI(E)EI1ARTICLE9949-9567
