This paper deals with the stability robustness prob- lem of a class of nominally linear systems subject t o time- varying parameter uncertainty. The allowable range of pa- rameter variation is assumed t o be an hyperrectangle in parameter space. The proposed robustness test, based on Lyapunov approach, requires a finite number of positivity tests of a quadratic form in correspondence of some salient points in parameter space.

Abstract
This paper deals with the stability robustness prob- lem of a class of nominally linear systems subject t o time- varying parameter uncertainty. The allowable range of pa- rameter variation is assumed t o be an hyperrectangle in parameter space. The proposed robustness test, based on Lyapunov approach, requires a finite number of positivity tests of a quadratic form in correspondence of some salient points in parameter space.File in questo prodotto:
