Abstract

Presents a tuning bilinear approximation method together with the interval arithmetic operation to convert a continuous-time (discrete-time) uncertain system to an equivalent discrete-time (continuous-time) uncertain model. The bounds of interval system matrices via the proposed interval tuning bilinear approximation method are narrower than those of the existing interval bilinear and the interval Pade approximation methods. The resulting interval models (the enclosing interval models) are able to tightly enclose the exact uncertain models
