ABSTRAKT

The paper deals with generalization of recursive (iterative) identification method for the single input and single output discrete dynamical systems with multiple modes under bounded uncertainty conditions. Generalization is conducted on the basis of modal decomposition of the system response with multiple eigenvalues. The influence of multiplicity both on the order recovering precision and the spectrum of approximating submodel is studied. It is illustrated, that the increasing modes multiplicity complicates a desired signal and noise separation and leads to expanding of eigenvalues localizing interval and reduction of modes multiplicity determination while identifying the systems with high values of multiplicity under bounded uncertainty conditions.
