Error State Convergence on Master–Slave Generalized Uncertain Neural Networks Using Robust Nonlinear $H_{\infty}$ Control Theory
研究了主从广义不确定神经网络在扰动和参数不确定下的鲁棒H∞控制问题，通过构造新的Lyapunov泛函和线性矩阵不等式设计控制器，实现误差同步系统的全局渐近稳定。
This paper addresses the convergence analysis on the guaranteed robust H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> control for master-slave generalized uncertain neural networks (GUNNs). Synchronization problems are raised up due to the existence of the disturbance loading and parameter uncertainties. In order to cope with the encountered robustness issues, a dual geometric sequence division-dependent augmented Lyapunov-Krasovskii functional is newly constructed, which contains state variable-based integral forms with unfixed intervals. Meanwhile, the convex combination technique is employed to deal with not only the parameter uncertainties but also the derivative of delay τ(t). To ensure the GUNNs to be globally asymptotically stable with the guaranteed H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> performance in the case of disturbance and parameters uncertainties, a controller is designed using the liner matrix inequalities technique. Numerical examples show that, in the sense of the prescribed H∞ performance, this proposed work achieves expected results on the error synchronization system.
