Research on system zeros: a survey

Abstract

Notable publications on zeros of multivariable systems are reviewed. Particular attention is paid to relationships between definitions of such zeros and their theoretical development. Transmission, invariant, system module, infinite, and finite zeros are addressed, the latter subdivided into a hierarchical structure with respect to information considered in the definition process.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
