| 摘 要： | 针对含完全未知时滞的不确定非线性系统的控制问题,提出了一种自适应模糊动态面控制方案.首先采用模糊逻辑系统逼近系统的未知时滞函数,进而用参考信号代换逼近器输入中的未知时滞信号,取消了对未知时滞常作的假设,摆脱了控制器构造对时滞假设条件的依赖性.模糊逼近和时滞代换产生的误差则采用自适应边界技术处理.基于Lyapunov-Krasovskii泛函,证明了闭环系统所有信号半全局一致最终有界,通过调节设计参数可以实现任意的跟踪精度.仿真实例进一步说明了该方案的可行性.

| Abstract: | An adaptive fuzzy dynamic surface control approach is proposed for the control problem of unknown nonlinear systems with completely unknown time delays.The unknown delay functions are approximated with fuzzy logic systems,and then the delay signals in the inputs of approximators are replaced by reference signals,so that the common assumptions on the delay signals are removed,and the dependency to time delay assumptions that traditional design needs is got rid of.Adaptive bounding technique is used to deal w... |
