本文研究ARMA线性子系统串联分段线性函数的Wiener系统的递推辨识问题.利用相关分析法和Yule-Walker方程给出线性部分参数的递推辨识算法,而对非线性部分参数用递推的最小二乘(LS)算法给出估计,并证明了这些算法都以概率1收敛到真值.
This paper deals with parameter identification of Wiener systems with a ARMA linear subsytem followed by discontinuous piecewise-linear function. Recursive agorithms are given for linear subsystems by using the correlation analysis and Yule-Walker equations, for discontinuous piecewise-linear function by using LS method. Strong consistency is proved for all estimates given in the paper.
