摘要
本文提出卷积方程的一种求解方法.它可用于根据实洲数据辨识一个参数未知的线性平移不变系统.利用所述方法可依次确定系统的阶数、极点和系数。最后,我们讨论了误差情况和给出了数值例子,表明所提出的方法是可行的。
In this paper, the fitting solvent for convolution equation is advanced.For given measure dada of the impulse response of a linear syatem, first, the order of the system can be determined by Gram technique, then the poles of the system can be detemined by Prony method and inverse problem method of differential equation, and the coefficients can continuously be detemincd by ordinary linear method. Lastly, the error is discussed and a numerical example is given. It Shows that these methods are reasonable and feasible.
