RESUMO

This study presents the theoretical foundations of multivariable data modeling in state space by Subspace Methods for Systems Identification of linear time invariant, discrete time, systems. The work contains some basic concepts of dynamic systems, a little of history and the elements of systems identification, state space models and extended state space models. Two Subspace Methods are analyzed and applied, Multivariable Output-Error State-sPace (MOESP)and Numerical algorithm for Subspace State-Space System IDentification (N4SID). Some modifications then are proposed and implemented. Experiments with benchmarks are realized to show the procedure of Identification by subspace and to evaluate the modified algorithms
