摘　　要：对变论域模糊控制器伸缩因子选取的易实现性和输出的实时性问题进行了讨论,给出了一种选择伸缩因子的新方法.该方法与积分型伸缩因子和指数型伸缩因子选择相比具有计算量小、参数少的特点.通过仿真给出了该伸缩因子参数选择的原则.结合间歇反应釜工程应用,将此伸缩因子设置在变论域模糊控制器模糊推理的前件和后件,验证了此伸缩因子的有效性:在保证高精度的基础上,输出能快速跟踪系统的输入,为变论域模糊控制器实际应用提供了一种有效的解决方案.The issues of easy implementation to select the contraction-expansion factor for variable universe fuzzy controller and the real-time control are discussed,and a new selection method is provided.Comparing with the integral and exponential type selections,the new contraction-expansion factor selection method takes the advantages of containing fewer parameters and consuming smaller computing resource.Then the parameter selecting rules are given by simulation,and applied practically to the exothermic batch reactor to set the fuzzy reasoning of the variable universe fuzzy controller.It is observed that the new contraction-expansion factor is effective to ensure not only high control precision,but also fast tracking ability,which gives a support to apply the variable universe fuzzy controller to practical control engineering.
