| 摘 要： | 针对一类未知非线性MIMO系统(多输入/多输出系统),应用“主导输入”的概念,基于神经网络理论提出一种直接自适应鲁棒解耦控制方法.该方法不仅保证了闭环系统的稳定,而且使外部干扰、神经网络逼近误差及输入对输出的交叉耦合对跟踪误差的影响衰减到给定的水平.

| Abstract: | Based on neural network by applying "dominant input" concept for a class of unknown nonlinear MIMO systems(multi-input / multi-output systems),the direct adaptive robust decoupling control scheme is proposed.It is shown that the proposed scheme guarantees the stability of the closed-loop system and achieves tracking performance idex,meanwhile the influences of external disturbance,neural network approximation error and the cross-coupling of input to output on the tracking error are reduced to a prescribed level. |
