非线性系统参数集员辨识的一种新方法

A New Method of Set Membership Identification for Nonlinear System Parameters

在噪声未知但有界的情况下，研究了非线性系统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．这种新方法为解决非线性系统参数的集员辨识问题提供了一种有效的可行方法。

Assuming that noise is unknown but bounded,set membership identification for nonlinear system parameters is studied in this paper.A two step method of set membership identification for nonlinear system parameters is presented,in which the center of parameters feasible solution set is estimated at first and then set's size is estimated.Thus an effective and feasible method is provided for solving set membership identification problems of nonlinear system parameters.The longitudinal simulation example of a certain flight vehicle indicates that the new method is very effective.
