摘　　要：针对一类状态可测的非线性大系统,提出了基于二型模糊逻辑系统的模糊自适应分散控制方法。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。A fuzzy adaptive decentralized control approach was suggested for a class of large-scale nonlinear systems based on interval type-2 fuzzy logic systems which were employed to approximate the unknown nonlinear function in both the design and the combination of fuzzy adaptive and the nonlinear decentralized control theory.A new type-2 fuzzy adaptive decentralized control was proposed.Lyapunov function method in use proved the stability of whole closed-loop system,with much better tracking performance.Simulation results expatiate in further verification,that the actual sample simulayed shows the effectiveness of the proposed method.
