Abstract

In this paper a unitary identification procedure for linear multivariable systems is described. The approach considered is based on a preliminary canonical structure identification, i.e. on the direct determination, from input-output sequences, of a set of invariant indexes completely describing the input-output structure of the system. Reduced computation time and storage, canonical representation of the identified model and easy estimation of the initial state of the system are in this way achieved. The results obtained from the application of this procedure to a simulated process and to a chemical reactor are also reported.
