Several stability criteria for N-dimensional linear shift-invariant discrete systems described in the state–space model are presented. The criteria are the N-D state–space versions of the De Carlo et al., Anderson-Jury and Lyapunov equations with

In this paper, a theorem for the instability checking of linear shift-invariant two-dimensional discrete systems is proposed. This is based on the results for the location of the roots of polynomials presented by Mori and the criterion for the stabil

Abstract This paper presents new stability conditions for two‐dimensional (2‐D) systems in state‐space description. Both discrete and continuous systems are studied. These results are based on the criteria first presented by Huang, De Carlo, St

During the past few decades, two and higher dimensional systems have been extensively applied in many areas of research. The representation of the 2-D systems in the frequency domain is usually given by its transfer function. The bounded-input bounde

The discrete time Lyapunov equation is used in many applications and there is interest in its inverse and direct solutions. New methods are proposed to obtain solutions for cases where the system matrix is in controllable canonical form. The approach
