   在引進(jìn)統(tǒng)一的模型結(jié)構(gòu)以后，利用隨機(jī)逼近原理，提出了各種在線(xiàn)識(shí)別算法的一般遞推形式。
2. This dissertation presented two new methods of robust adaptive track control for a class of mimo strong nonlinear system with external disturbance . one method makes use of taylor approximation principle to linearize the mimo strong nonlinear system at the ideal equilibrium point , meanwhile external disturbance is considered , and then designs two on - line neural network controller respectively , which can dynamically compensate the high order items of taylor series and the control signals at ideal equilibrium point under the drive of state error between linear and nonlinear system . a linear feedback controller obtained by pole assignment and two on - line neural network act on the practical mimo high nonlinear system together , guaranteeing the whole system robust stable and tracking the specified signal ; the other method designs three on - line neural networks for this class of system
   本文對(duì)于一類(lèi)含有外部擾動(dòng)的多輸入多輸出( mimo )強(qiáng)非線(xiàn)性系統(tǒng)，提出了兩種新的魯棒自適應(yīng)跟蹤控制方法，第一種利用了taylor近似的原理，在考慮了外部擾動(dòng)的情況下，將mimo強(qiáng)非線(xiàn)性系統(tǒng)在理想平衡點(diǎn)處線(xiàn)性化，分別設(shè)計(jì)了兩個(gè)在線(xiàn)神經(jīng)網(wǎng)絡(luò)控制器，在線(xiàn)性和非線(xiàn)性系統(tǒng)之間的狀態(tài)誤差驅(qū)動(dòng)下動(dòng)態(tài)補(bǔ)償系統(tǒng)的taylor近似高階項(xiàng)及理想平衡點(diǎn)處的控制信號(hào)，滿(mǎn)足極點(diǎn)配置方法的線(xiàn)性反饋控制器和兩個(gè)在線(xiàn)神經(jīng)網(wǎng)絡(luò)聯(lián)合作用于實(shí)際的被控mimo強(qiáng)非線(xiàn)性系統(tǒng)，在保證整個(gè)系統(tǒng)魯棒穩(wěn)定性的情況下，能夠跟蹤給定的指令信號(hào)；另一種方法是針對(duì)這類(lèi)系統(tǒng)設(shè)計(jì)了3個(gè)在線(xiàn)神經(jīng)網(wǎng)絡(luò)，分別實(shí)時(shí)抵消這類(lèi)非線(xiàn)性系統(tǒng)中的非線(xiàn)性部分、與控制量耦合的非線(xiàn)性項(xiàng)以及外部擾動(dòng)，使得受控系統(tǒng)的輸出可以完全跟蹤給定輸入?yún)⒖夹盘?hào)。
