摘要
介绍了一种传统模糊PID控制器规则库的构建方法 ,这种方法基于对过程一般动态性能的分析 ,直观地得出规则库 ,克服了由先验知识构造规则库造成的主观影响 ,具有一定的通用性。通过分析规则库中各个规则与系统响应各个阶段的联系的基础上 ,提出了一种通过改变隶属函数来提高模糊控制器性能的方法。
A methodology is introduced for building the rule base of conventional fuzzy logic controller(FLC).Based on the analysis of general dynamic behaviour of the process,this kind of methodology can get the rule base visually.It is generally and overcome the subjective influence caused by future knowledge which is used to build urle base before.By analysising the relationship between the rules in the base and the stages of the systemic response,a new methodology is brought forward.The methodology improve the performance of FLC by way of turn the Membership Functions(MFs).
