  • Abstract
    We propose a new method for approximating time-delays in dynamical systems. A weighted H∞ norm criterion is minimized to obtain rational approximation of e-sd. We report the approximation in a diagram relating both the amount of time delay and the bandwidth to the order of the approximating rational function for a given level of infinity norm. The obtained approximations are compared to the widely used Pade´s approximation. Examples are used for illustrations
