摘要：
The purpose of this paper is to use the Passivity Theorem to derive new stability conditions for a class of systems that consist of a linear subsystem with parametric uncertainty and nonlinear feedback. To address the inherent conservativism in applying the Passivity Theorem, causal multipliers are introduced into the analysis and it is shown that a Popov-like stability condition results. The stability results are then extended for noncausal multipliers using the notion of positivity.
