| Abstract: | If one can transform a nonlinear system into observer normal form, it is possible to design an observer with exactly linear error dynamics. Unfortunately, many systems of practical relevance violate the existence conditions of the normal form. This drawback can be circumvented by means of an approximate observer normal form. The actual computation of the associated transformation may still be very difficult. We suggest a nonlinear observer design procedure that avoids this drawback. (© 2006 WILEY-VCH Verlag GmbH & Co.
