Subsequently , a scheme of modeling unknown nonlinear systems is presented . in it a feedforward structure of wavelet neural networks is adopted , and with a hybrid error performance index , a novel on - line dynamic gradient algorithm for training neural networks is put forward . as a result , the real system state and the derivative of the state are accurately identified at the same time , thus a more accurate network model is obtained 随后考虑了对未知非线性动态系统进行建模的方案,其中采用了前向的小波神经网络结构,通过选取一种混合的误差性能指标,提出一种新的在线动态梯度算法训练神经网络,使得最终实现对未知系统状态及其导数(系统函数)同时精确辨识,从而得到一个较为精确的网络模型。
