Two-Port Networks

Part of the Advances in Industrial Control book series (AIC)


This chapter will briefly introduce two-port network descriptions which are closely related to that of the general control framework involving descriptions using LFT and CSD. The two-port network was developed as a common methodology to describe the relationship between inputs and outputs of an electrical circuit. For example, the impedance matrix of a two-port network can be determined by each port’s voltage and current according to Ohm’s law. The exposure in this book will focus on both scattering (i.e., LFT) and chain scattering (i.e., CSD) parameters as well as their applications to the modern control theory.
