| 摘 要： | 针对一类不确定非线性时变时滞系统,提出了一种简化的自适应模糊动态面控制方法.该方法取消了对系统时滞常做的假设.仅采用一个模糊逼近器便使所有的未知函数得到补偿,简化了控制器的结构.通过构造合适的Lyapunov-Krasovskii泛函,闭环系统的所有信号被证明为半全局一致最终有界.仿真实例进一步验证了控制方案的有效性.

| Abstract: | A simplified adaptive fuzzy dynamic surface control approach is proposed for a class of uncertain nonlinear time-varying time-delay systems. The common assumptions on the time-delays of the system are not required; only onefuzzy approximator is needed for compensating all the unknown functions. Thus, the structure of the controller is simplified. By constructing an appropriate Lyapunov-Krasovskii functional, we proved all the signals of the closed-loop system are semi-globally uniformly bounded. Simulation results are presented to demonstrate the effectiveness of the proposed control approach. |
