摘要

本文将增长的小波级数模型与Ｌｙａｐｕｎｏｖ综合方法相结合，提出了一种对连续非线性动态系统的在线辨识策略．增长模型的概念克服了事先确定模型结构所带来的欠模型或模型冗余问题．由Ｌｙａｐｕｎｏｙ综合方法导出的参数调整律保证了辨识策略的全局稳定性和模型参数的收敛性

Abstract

This paper presents an online identification scheme for continuous nonlinear dynamic systems by combining the growing wavelet series model with Lyapunov synthesis approach.The introducing of growing model overcomes the problem of overdetermined or underdetermined model structure brought by choosing model structure a priori.The stability and convergence of the overall identification scheme are guaranteed by parameter adjustment laws developed by using the Lyapunov synthesis approach.
