这篇论文扩大适应神经网络(NN ) 控制途径到未知输出反馈的一个类非线性的时间延期系统。追踪控制器的适应产量反馈 NN 被走技术的背设计。NN 准时习惯于近似未知功能依赖者延期。延期依赖者过滤器为州的评价被介绍。支配方法被用来处理光滑的时间延期基础功能。适应的跳技术被采用估计 NN 近似错误的上面的界限。基于 Lyapunov-Krasovskii 功能,在靠近环的系统的所有信号的半全球的一致最终的围住的海角被证明。可行性被二个解说性的模拟例子调查。
This paper extends the adaptive neural network (NN) control approaches to a class of unknown output feedback nonlinear time-delay systems. An adaptive output feedback NN tracking controller is designed by backstepping technique. NNs are used to approximate unknown functions dependent on time delay, Delay-dependent filters are introduced for state estimation. The domination method is used to deal with the smooth time-delay basis functions. The adaptive bounding technique is employed to estimate the upper bound of the NN approximation errors. Based on Lyapunov- Krasovskii functional, the semi-global uniform ultimate boundedness of all the signals in the closed-loop system is proved, The feasibility is investigated by two illustrative simulation examples.
