Observability and reconstructibility of singular 2-$$D$$ systems. (English) Zbl 0739.93017
Summary: Notions of global and causal observability and reconstructibility are extended for singular 2-$$D$$ linear systems. Necesary and sufficient conditions for the global and causal observability and reconstructibility for the singular 2-$$D$$ Fornasini-Marchesini model are established.
