Technical Report of the ISIS Group
at the University of Notre Dame
This report covers open-loop conditions that guarantee closed-loop stability of a feedback
interconnection of two systems. The traditional solutions for this problem are passivity theory
and the small gain theorem. These approaches can be shown to be part of a larger design
framework. Two such larger frameworks are the conic systems framework and the passivity
index framework. This report shows that these two actually reduce to the same open-loop
conditions on the two systems in the interconnection. This connection is shown for the purpose
of applying this generalized framework to switched systems. The recent application of passivity
to switched systems gives one method of guaranteeing that the feedback interconnection of two
