✦ Synopsis

paper describes how the state-space basis of models identified with subspace identification algorithms can be determined. It is shown that this basis is determined by the input spectrum and by user-defined input and output weightings. Through the connections between subspace identification and frequency-weighted balancing, the statespace basis of the subspace-identified models is shown to coincide with a frequency-weighted balanced basis.

The problem of Linear Multivariable State Space model identification from input-output data can under the presence of process-and measurement noise be solved in a non-iterative way when incorporating instrumental variables constructed from both input and output sequences in the recently developed cl
