A Survey on Method of System Identification
In this paper the advance in the study of system identification is summarized. Some traditional system identification methods are introduced, Least Squares Method, Recursive Gradient Correction and Recursive Maximum Likelihood. Some disadvantages are introduced too so that some new identification methods based on neural network, genetic algorithms, fuzzy logic and wavelet network are presented. After all, one system identification method based on adaptive filter ,the method has been usually used in active vibration control.
