动态非线性模型参数多层递阶估计法

针对目前通用的动态系统状态预报方法的不足，提出关于动态非线性模型参数估计的多层递阶估计法，并对预报误差的原因进行分析，使预报精度得到提高。

Multistage Estimation Methods of Dynamic Nonlinear Model Parameter

Forms the multistage system which is used as the state prediction. At present, the use of the usural prediction method is limited for the logner the prediction period is, the larger the prediction error is. This article means to introduce the multistage estimation methods of dynamic nonliear model parameter, and analyses the error of the prediction, expected to improve the precis of prediction.
