针对具有未知常值控制增益的非线性切换系统,提出了一种直接自适应神经网络控制方法。多层神经网络(MNN)被用作一种工具,用于建模非线性函数的小误差容限。利用切换多李雅普诺夫函数方法导出了自适应更新律,并给出了一种采用平均驻留时间技术的容许切换信号。证明了所得到的闭环系统是渐近李雅普诺夫稳定的,使得输出跟踪误差性能良好。最后,通过两个Duffing强迫振荡系统的仿真实例验证了所提控制方案的有效性。
This paper is concerned to present a direct adaptive neural control scheme for switched nonlinear systems with unknown constant control gain. Multilayer neural networks (MNNs) are used as a tool for modeling nonlinear functions up to a small error tolerance. The adaptive updated laws have been derived from the switched multiple Lyapunov function method, also an admissible switching signal with average dwell-time technique is given. It is proved that the resulting closed-loop system is asymptotically Lyapunov stable such that the output tracking error performance is well obtained. Finally, a simulation example of two Duffing forced-oscillation systems is given to illustrate the effectiveness of the proposed control scheme.
