飞行器气动参数的集员辨识

SET MEMBERSHIP IDENTIFICATION FOR FLIGHT VEHICLE AERODYNAMIC PARAMETERS

在噪声未知但有界的情况下，本文研究了飞行器气动参数的集员辨识问题。提出了先对非线性系统参数可行集的中心进行估计，再估计参数可行集大小的集员辨识两步法。这样就为解决飞行器气动参数的辨识问题提供了一种新的可行方法，再入体实测数据的处理表明这种方法十分有效。

Assuming that noise is unknown but bounded,set membership identification problem for flight vehicle aerodynamic parameters is studied in this paper.A two step method of set membership identification for nonlinear system parameters is presented,in whitch the center of parameters feasible solution set is estimatet at first and then the set′s size is estimated.Thus a new and feasible method is provided for solving set membership identification problems of flight vehicle aerodynamic parameters.Processing of real measured data for reentry body indicates that the method is very effective
