Continuous-time to discrete-time conversion via a novelparametrized s-to-z-plane mapping

摘要

A parametrized s-to-z-plane map is introduced, where thenconventional bilinear map and backward and forward Euler rules appear asnspecial cases. Time and frequency-domain characteristics of the map arendiscussed, along with a simple technique for applying this map tonadaptively reduce truncation error in the continuous-time tondiscrete-time conversion problem. An example illustrates the method andnits potential for yielding more accurate discrete-time models overnconventional approaches
