摘　　要：为了准确识别闭环控制系统中存在的扰动源并消除其隐藏在系统中的干扰规律,在对函数P-集合(function packet sets)的动态特性和规律特性进行进一步的推理挖掘的基础上,提出了F-萎缩规律、F-扩张规律、(F,F)-双向规律对及F-萎缩规律簇、F-扩张规律簇、(F,F)-双向规律簇的概念,给出了萎缩度、扩张度及萎缩度集合、扩张度集合的定义,并将其运用到闭环控制系统干扰规律的识别过程中,提出了(F,F)-双向规律扰动识别准则,构建了基于函数P-集合的闭环控制系统模型。经试验验证,给出的方法是有效的,同时为实际生产生活中干扰规律的识别与抵消提供了一个新的工具。To recognize the disturbance source existing in the closed-loop control system,and to eliminate the disturbance lawhidden in the system,Inferring and minding further about the dynamic characteristic and lawcharacteristic of function P-sets（ function packet sets）,the concepts of 珔F-shrinking law,F-extending law,（ 珔F,F）-two directions lawpair,珔F-shrinking lawclusters,F-extending lawclusters,and（ 珔F,F）-two directions lawclusters were proposed,and definitions of shrinking degree,extending degree,shrinking degree set and extending degree set were given,which were used to identify the disturbance lawexisting in closed-loop control system. The disturbance recognition rule of（ 珔F,F）-two directions lawwas presented,and the model of closed-loop control system basing on function P-sets was constructed. After experimental verification,it could be found that the given method was effective,while it provided a newtheoretical tool for the recognition and cancellation of disturbance lawin the actual production and living.
