On the singular Fornasini-Marchesini model of 2-D discrete systems

The singular Fornasini-Marchesini model of 2-D discrete systems cannot be handled by commonly used z-transform techniques. A recursive form of the basic equation is found, and consequently existence and uniqueness theorems can be formulated. The recursive form of the singular Fornasini-Marchesini model also yields a sufficient stability condition for this model. A detailed example illustrates the results.<
