furthermore, no linearity with respect to unknown system parameters is assumed . the robustifying term in the observer can reduce the error brought by the wavelet network approximation greatly . the overall adaptive scheme is shown to be uniformly ultimately bounded 文中給出了小波網(wǎng)絡(luò)參數(shù)的在線自適應(yīng)調(diào)節(jié)律,通過觀測器中的魯棒項(xiàng)可以減小網(wǎng)絡(luò)重構(gòu)對狀態(tài)估計(jì)的影響,給出了此類小波網(wǎng)絡(luò)自適應(yīng)觀測器的基于lyapunov理論的穩(wěn)定性證明。
