ABSTRACT: This paper addresses the
new algebraic test to check the aperiodic stability of two dimensional linear
time invariant discrete systems. Initially, the two dimensional characteristics
equations are converted into equivalent one-dimensional equation. Further
Fuller’s idea is applied on the equivalent one-dimensional characteristics
equation. Then using the co-efficient of the characteristics equation, the routh
table is formed to ascertain the aperiodic stability of the given two-dimensional linear discrete system. The illustrations were presented to show the
applicability of the proposed technique.
