First estimates of Wiener and Hammerstein systems using multisine excitation
P. Crama, Johan Schoukens · 2002
This paper presents fast methods to obtain a first estimate of Wiener or Hammerstein systems. For this purpose, a special excitation signal is introduced: the random phase multisine. Its properties are briefly stated and used in both methods. The methods are tested with simulations and compared with similar methods available in the literature. The paper finishes with an application of the presented methods to real-world measurements.
