Detection of Unmodeled Nonlinearities Using Correlation Methods
2007 (English)In: Proceedings of the 2007 IEEE Instrumentation and Measurement Technology Conference, 2007, 1-6 p.Conference paper (Refereed)
This paper concerns the validation of linear models with respect to unmodeled nonlinearities. Two versions of a method for nonlinearity detection based on estimators of higher order cross-correlations are described and evaluated. Unlike many existing approaches, the proposed method seems to be applicable to a wide range of systems and input signals. It can also distinguish between even and odd nonlinearities.
