The behavior of identifiers and adaptive observers in the presence of parasitics is analyzed. Bounds for the state/parameter error are established. The adaptive schemes considered are shown to be robust provided the input signal is rich for the dominant modes, but does not contain high frequencies in the parasitic range. The bounds indicate possibilities for reducing the error by a proper choice of the input signal. Copyright © 1982 by The Institute of Electrical and Electronics Engineers, Inc.
