| 摘 要： | 针对多输入多输出非线性多时滞系统，提出了一种直接自适应模糊跟踪控制方案．该方案有机综合了自适应控制和H∞ 控制，构建了一种自适应时滞模糊逻辑系统用来逼近有多重时滞的未知函数；设计了H∞ 补偿器来抵消模糊逼近误差和外部扰动．根据跟踪误差给出了参数调节规律，构造了包含时滞的李亚普诺夫函数，从而证明了误差闭环系统满足期望的H∞ 跟踪性能．仿真结果表明了该方案的可行性．

| Abstract: | This paper presents a direct adaptive fuzzy tracking control scheme for MIMO nonlinear systems with multiple time delays.The scheme organically synthesizes adaptive control and H_∞ control.A kind of adaptive timedelay fuzzy logic systems are constructed and used to approximate the unknown functions with multiple time delays.An H_∞ compensator is designed to eliminate fuzzy approximation errors and external disturbances.The adjusting laws for parameters are derived by the tracking error.The Lyapunov function with time delays is constructed,and then it is proved that the error closed loop system satisfies the anticipant H_∞ tracking performance.The simulation results show the feasibility of the control scheme. |
