摘要
本文提出了一种用Fourier级数来估计延时双线性系统模型参数的新方法.通过Fourier级数的延时分析法,把原延时双线性系统方程转换成可用输入输出信息来确定待定参数的代数方程,最后用最小二乘法得到参数的估计值.与Walsh级数方法相比本文给出的运算矩阵精确度更高,并且在输入信息是正弦信号时,计算过程相当简洁.
A new method of parameter estimation via Fourier series for time-delay bilinear systems is presented. By time-delay analysis, the bilinear systems can be expressed by algebric equations, whose parameters can be identified by input and output information. Compared with Walsh function approaches, the computing matrices given in this paper are more accurate, and when the input is a sinusoidal signal, the computation procedure is much more simple.
