Stability of 2-D digital filters described by the Roesser model using any combination of quantization and overflow nonlinearities
A novel linear matrix inequality (LMI)-based criterion for the global asymptotic stability of two-dimensional (2-D) state-space digital filters described by the Roesser model employing various combinations of quantization and overflow nonlinearities is presented. The criterion is less restrictive than a previously reported criterion.
