| 摘 要： | 针对多输入多输出非线性系统,把自适应模糊控制和自适应模糊辨识结合起来,提出了一种间接自适应模糊控制方案.由跟踪误差和辨识误差给出了参数调节规律,两种误差同时调节参数改善了系统性能.应用推广的模糊逻辑系统来估计多维未知函数,补偿器可抵消模糊逼近误差和外部扰动.控制方案保证了系统的稳定性,实现了跟踪.

| Abstract: | Combining the adaptive fuzzy control with the adaptive fuzzy identification, this paper presents an indirect adaptive fuzzy control scheme for MIMO nonlinear systems. By using the tracking error and the identification error, the parameter adjusting laws are derived. Both errors improve the performance of the system by regulating the parameters. Extended fuzzy logic systems are used to estimate the multidimensional unknown functions, and the compensator eliminates fuzzy approximation errors and external disturbances. The control scheme guarantees the system stability and attains tracking. Simulation results demonstrate that the control scheme is effective. |
