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
隨后考慮了對(duì)未知非線性動(dòng)態(tài)系統(tǒng)進(jìn)行建模的方案，其中采用了前向的小波神經(jīng)網(wǎng)絡(luò)結(jié)構(gòu)，通過(guò)選取一種混合的誤差性能指標(biāo)，提出一種新的在線動(dòng)態(tài)梯度算法訓(xùn)練神經(jīng)網(wǎng)絡(luò)，使得最終實(shí)現(xiàn)對(duì)未知系統(tǒng)狀態(tài)及其導(dǎo)數(shù)(系統(tǒng)函數(shù))同時(shí)精確辨識(shí)，從而得到一個(gè)較為精確的網(wǎng)絡(luò)模型。
