New results in 2-D systems theory, part II: 2-D state-space models—Realization and the notions of controllability, observability, and minimality

Abstract

In this part, a comparison between the different state-space models is presented. We discuss proper definitions of state, controllability and observability and their relations to minimality of 2-D systems. We also present new circuit realizations and 2-D digital filter hardware implementation of 2-D transfer functions.
