| 摘 要： | 针对一类状态不可测的非线性大系统,首先设计一种误差观测器,然后设计一种自适应输出反馈模糊控制器。在设计中,应用二型模糊逻辑系统逼近系统中的未知函数,结合模糊自适应和非线性分散控制设计理论,给出了一种新的二型模糊自适应分散控制方法,基于李亚普诺夫函数方法证明了整个闭环系统的稳定性,而且取得很好的控制跟踪性能。仿真实例进一步验证了所提方法的有效性。

| Abstract: | Against a class of nonlinear large-scale systems with the unmeasured states,the error observer was firstly designed,then a fuzzy adaptive decentralized control was designed.Interval type-2 fuzzy logic systems were employed to approximate the unknown nonlinear function,in combining the theory on a fuzzy adaptive and nomlinear decentralized control to be designed,a new type-2 fuzzy adaptive decentralized control method was proposed.Lyapunov function in use proved that the proposed fuzzy adaptive decentralized... |
