Distributed System Simulation With Bilateral Delay-Line Models

Abstract

Consideration of general linear models for transmission line systems (hydraulic, pneumatic, electrical, etc.) has so far been limited to the case of systems in which the lines exhibit no internal dispersion. In this paper, a simulation system for distributed dynamic systems which can include dispersive transmission elements will be described. The ideal transmission line, a lossless, nondispersive transmission line, is used with static junctions to form models of dynamic systems. A simple computational algorithm is obtained if the state of the model is expressed in terms of wave-scattering variables rather than by the pressure-flow or voltage-current type of state variables. A model for dispersive transmission lines is presented, and its feasibility is demonstrated.
