PhD Thesis |
Title:
“Analysis of Linear, Discrete-time, Singular systems” Abstract The subject of the PhD thesis is the study of singular linear discrete time systems. The regular first-order case has been studied by several authors in the past, mainly from an algebraic and geometric point of view. The main objective of the present study is to extend these results towards three directions. In particular, the analysis of non-regular first-order singular systems, the study of the structure of the solution space (behaviour) of auto-regressive (AR) representations and a solution method for auto-regressive moving average (ARMA) representation using the fundamental matrix sequence. The structure of the solution spaces has been directly connected to the algebraic structure of the polynomial matrices describing the corresponding systems while special attention has been given on the infinite algebraic structure of the matrices involved.
