摘要
建立了一种回归神经网络辨识非线性液压作动器系统数学模型的辨识方法,研究了基于回归神经网络内部状态反馈的辨识算法,利用辩识实验获得的过程输入/输出数据动态调整神经网络权值。仿真结果辨明:回归神经网络描述的液压作动器系统数学模型具有较高精度,算法全局逼近能力良好。
The method of identitying was built to identify mathematical model of nonlinear hydraulic actuator system. The algorithm of identifying was researched base on inner state feedback of recurrent neural networks. The weights of neural networks were dynamic adjusted by input/output data of process that it was acquired by experiments of identifying. The result of simulation shows that mathematical model of neural networks of hydraulic-gas Actuator system has better precision and algorithm has ability to approximate error of global.
