| 摘 要： | 首先讨论了非线性系统的拟合推估线性化算法、迭代算法和顾及二次项的非线性算法,推导了相应计算公式。证明了非线性拟合推估理论是线性拟合推估理论的拓展,线性拟合推估是非线性拟合推估的一个特例。

| Abstract: | This paper first discusses the arithmetic of linearization.The iterative and nonlinear arithmetic considering square terms are dissertated too.Then a computing formula is educed.The theory of nonlinear collocation is proved to be an enlarging one for linear collocation.That is to say,the theory of linear collocation is a special example of nonlinear collocation. |
