Input-Output Multistructural Models in Multivariable Systems Identification

In this paper a class of input-output multistructural (overlapping) models is developed starting from the usual state-space ones. The algebraical link between state-space and input-output multistructural models is then investigated. The problems arising in the use of input-output multistructural models in the identification of multivariable systems are finally discussed and a procedure based on the use of these models proposed.
