Abstract
Algebraic necessary and sufficient conditions for the stability analysis of 2-D discrete systems are presented. These conditions are developed based on the frequency-dependent formulation of the Lyapunov equation using Kronecker products. It is shown that these necessary and sufficient conditions for internal stability of 2-D discrete systems are equivalent to testing the eigenvalues of constant matrices. This is a simplification over earlier tests which require testing the positivity of one or more functions of ω for all ω ε[0,2π]
