Wavelet-based Non-linear System Identification

A novel method for identification of non-linear systems is proposed to solve the problem of the estimating the unknown parameters of non-linear systems. For Haar wavelet is a set of complete, orthogonal basis and is easy to computation, so it has significant advantage in system identification and also has been applied to many other fields. Therefore, we as well utilize Haar wavelet to analyses all time functions and estimate the unknown parameters. Finally, simulation results with or without noise respectively verify the effectiveness of our method.
