摘　　要：本文给出了一种改进的Ｆｏｕｒｉｅｒ级数辨识延时线性系统的算法。通过Ｆｏｕｒｉｅｒ级数的运算算子矩阵，将描述系统的微分方程化为代数方程，再使用最小二乘方法即可求得系统的参数估计。本文的算法简单，节省了ＣＰＵ存贮空间，更便于实用。in this paper,the algorithm to the parameter estimation of linear delayed systems via Fourier series is (?)en.With the operational matrices of the Fourier series,the differential equations of describing system are transformed into the algebraic equations.Using the least square method,we can get the estimation of parameters.The algorithm which reduces the store space of CPU is simple and more convenient for practical use.
