摘　　要：阐述了常用的变论域模糊控制伸缩因子,对常用的自然指数形伸缩因子算法进行了改进,构建了一种运算量比较少且编程容易实现的伸缩因子,从数学角度证明了算法的合理性。通过把改进的伸缩因子算法移植于变论域模糊控制系统中,对某一阶非线性不稳定系统进行控制,通过MATLAB仿真,证明了该伸缩因子算法不仅能取得自然指数形伸缩因子算法同样的效果,而且算法从很大程度上提高了控制系统的实时性,从而为算法在实际的工程应用中提供了一定的参考价值。This paper introduces several shrinkage factors of variable universe fuzzy control alogrithm.A new shrinkable factor that based on natural index is proposed,which is not only simply calculated,but also is easily realized.And it is proved to rationality from the mathematical point of view.The shrinkage factor of variable universe fuzzy control has been tested and verified in a certain type of first-order nonlinear unstable system.Simulation results show that the shrinkage factor can achieve the same effect of a natural index shrinkage factor algorithm.
