Relaxed global asymptotic stability of 2-D state-space digital filters described by Roesser model with polytopic-type uncertainty
The global asymptotic stability of uncertain 2-D state-space digital filters is obtained. The criterion takes the form of an LMI which is computationally tractable. A new Lyapunov function for 2-D state-space digital filters is proposed. A kind of matrix transformation technique is developed.
