BP算法在非线性系统参数辨识中的应用

BP Algorithm Apply to Identification of Non -linear System's Parameter

非线性系统很少有精确的数学模型,因此,很难就系统提出一个良好的控制方法。为了解决这一问题,本文用人工神经网络来辨识非线性系统,并着重介绍其学习算法BP算法。

As non - linear system seldom has accurate arithmetic model. It is very difficult to propose a good controlling method for it. To solve this problem, the writer of this article suggests that artificial nervous network be employed in identification of the system, and lays emphasis on presentation of its algorithm___BP algorithm.
