  • Abstract
    An extended Lyapunov theory has been developed for checking the stability of nonstationary two-dimensional (2-D) systems. This development uses the wave model introduced by W.A. Porter and J.L. Aravena (1984). The analysis, using the Lyapunov method on the wave model, highlights the basic difficulty in stability studies for m -D systems. In utilizing the 1-D nature of the wave model, the, Lyapunov equations are time variant (TV), even for constant matrices in the Givone-Roesser model. This TV characteristic invalidates the standard necessary and sufficient conditions available for stationary, 1-D systems. However, as the study shows, it is relatively straightforward to generate necessary or sufficient conditions
