| 摘 要： | 研究了利用极大似然理论进行有控飞行器气动参数辨识的问题，首先介绍了牛顿－拉夫逊（ＭＮＲ）简化算法，然后，提出了采用此入外部激励的办法进行气动参数辨识，这种方法可增强参数的可辨识性，最后提出了构造故障弹道辨识气参数的设想，由于特定的故障弹道和外加激励一样，不同程度地激发了导弹的飞行信息，故辨识结果较好。

| Abstract: | In this article, the problem of how to estimate aerodynamic parameters of controlled flight vehicle by the method of maximum likelihood estimation is analyzed. First, introduces MNR algorithm. And then,in order to identify the parameters the outside input is ushered. The method of fault trajectory was proposed in final. Because the selected fault trajectory can stimulate the state of flight, parameters can be identified very well. |
