摘要
对于在线辨识非线性系统，传统的小波网络缺乏有效的算法。本文在正交小波网络的基础上，提出一种利于实时应用的可变正交小波网络，给出了其结构变化和参数调整的策略，并对建模误差的变化进行了分析。最后用于辨识非线性动态系统，仿真结果验证了该方法的可行性和有效性。
Conventional wavelet networks are short of effective algorithms for on-line identifying nonlinear dynamic systems. A kind of variable orthogonal wavelet networks which can be on-line used conveniently is proposed,relative variable strategy and operation are defined accordingly. Analysis of modeling error is also given. As example, two nonlinear dynamic systems are identified using the provided method,the results of simulation shouw that it is effective and feasible.
