Passive Testing of Timed Systems [PDF]
, 2008 This paper presents a methodology to perform passive testing based on invariants for systems that present temporal restrictions. Invariants represent the most relevant expected properties of the implementation under test. Intuitively, an invariant expresses the fact that each time the implementation under test performs a given sequence of actions, then

Balancing of Lossless and Passive Systems [PDF]
IEEE Transactions on Automatic Control, 2008 Different balancing techniques are applied to lossless nonlinear systems, with open-loop balancing applied to their scattering representation. It is shown that they all lead to the same result: the pair of to-be-balanced functions is given by two copies of the physical energy function, yielding thus no information about the relative importance of the ...

On Passivity Analysis and Passivation of Event-Triggered Feedback Systems Using Passivity Indices
IEEE Transactions on Automatic Control, 2017 While most of the work in the literature focuses on stability conditions for event-triggered systems, in this technical note we focus on passivity and passivation of event-triggered feedback interconnected systems of two input feed-forward output-feedback (IF-OF) passive systems.
