| 摘 要： | 本文提出了一种全新的双线性模型参数递推估计算法，其机理是通过采用泰勒级数来逼近似然函数，因此复杂的非线性参数估计就变成了较容易的线性参数估计，两组仿真实例以及在颤振分析中的应用表明，本算法具有快，稳定及精度较高等特点。

| Abstract: | A new recursive least-squares algorithm is proposed for estimating parameters of the bilin-ear model.The proptned algorithm is obtained by using Taylor series to approximate a ccat function, therefore, the difficuIt nonlinear parameter estimation problem becomes an easy linear paran1eter esti-mation problem,Two simulation exan1ples as Whll as chatter of turning a slender shaft are presented toshow that this method is available to the pratical situation because of its simplicity and rapidity. |
