Observability and reconstructibility of the 2-D Fornasini-Marchesini model

Notions of global and causal observability and reconstructibility of the model are presented. The necessary and sufficient condition for the existence of these properties are formulated. The conditions are given in terms of 1-D system observability and reconstructibility, so that well-known tests for those systems can be used to check the observability and reconstructibility of the 2-D systems. Some relations between these properties are also presented.<
