Abstract
This paper introduces a new approach for the identification of coupled map lattice models of spatio-temporal patterns from measured data. The nonlinear functionals describing the evaluation of the spatio-temporal patterns are constructed using B-spline wavelet and scaling functions. This provides a multiresolution approximation for the under laying spatio-temporal dynamics. An orthogonal least squares algorithm is used to determine the suitable terms from wavelet functions to form an accurate respresentations of the nonlinear spation-temporal dynamics. Three examples are used to demonstrate the application of the proposed new approach.
