本文从神经网络应用于动态系统建模的过程出发，指出了研究神经网络模型一般特性的重要性，分析了传统模型回响测试中存在的问题，给出了正确的回响测试方法，继而讨论了神经网络模型作为一类非线性动态模型所存在的多平衡点、极限环等问题，给出了模型稳定性判定的基本方法。最后是上述理论应用的一个示例。 Based on the application of neural network in dynamic system modeling, this paper points out the importance of studying the general characteristics of neural network model, analyzes the problems existing in traditional model echo testing, gives the correct reverberation test method, and then discusses the neural As a kind of non-linear dynamic model, such as the equilibrium point and the limit cycle, the network model is given and the basic method of model stability judgment is given. Finally, an example of the above theoretical application.
