Abstract

A data driven orthogonal basis function approach is proposed for non-parametric FIR nonlinear system identification. This eliminates the problem of blindly choosing the basis functions without a priori structural information. Extension to deterministic inputs are also presented. Further, based on the proposed basis functions, approaches are proposed for model order determination and regressor selection along with their theoretical justifications.
