摘要
利用正交多项式序列与Ｔａｙｌｏｒ级数之间的线性关系，给出了精确的乘积系数矩阵的定义及乘积变换式。利用正交多项式序列的正交性及微分算子矩阵，论述了时变非线性分布参数系统参数估计的正交多项式法。
The product coefficient matrix is improved using linear relation between Taylor series and orthogonal polynomial series.The accurater definition of the product coefficient matrix is given.New method of parameter estimation for time varying non linear distributed systems is proposed in term of orthogonality of orthogonal polynomial and differential operation matrix.
