identification of Multivariable Systems Using Steady-state Mode Parameters

摘要

The paper has developed the updated method for identification of multivariable linear systems described by the state space model using the approximate steady-state mode parameters which are defined by the integration of experimentally obtained output signals under the harmonic excitation on the input. The method allows one to update the model of dimension maximum permissible by stability condition to make it possible to approximate the real system output with accuracy consistent with errors in the obtained data.
