Nonlinearity Detection and Impulse Response Estimation Using a Weighting Approach
2009 (English)In: Proceedings of 15th IFAC Symposium on System Identification, 2009, 628-633 p.Conference paper (Refereed)
In this paper, two applications of a particular weighting method are described. The first application concerns a nonlinearity test for system identification problems. Starting with a validated linear model, it turns out to be possible to detect nonlinearities from the variations in the linear approximations that are obtained for different input signal distributions. The method is computationally efficient and can be used on a single dataset. The second topic of the paper is an improved weighting method for identification of the linear subsystems in Wiener or Hammerstein systems.
