利用Fourier级数对时滞系统的参数估计

Parameter Estimation of Time-delay Systems Via Fourier Series

利用Fourier级数来求解时滞系统的参数估计问题。提出的算法类似于利用其它的正交函数系所得到的算法。由于Fourier积分运算矩阵和滞后运算矩阵中的大多数元都是零元涸此计算特别简单。数值例子说明了用这种方法解决所考虑的问题可以得到满意的结果。

The Fourier series are used to solve the problems of parameter identification of time-delay system. The algorithms presented are similar to those already dervied with other orthogonal functions. Since most elements of the Fourier integration operational matrix and Fourier delay operational matrix are zero, the computation is more simple. A numerical example shows that satisfactory computational results are obtained by using the new approaches to solve the considered problems.
