基于并规则的模糊PID控制器的设计与仿真

Design and Simulink of PID Fuzzy Controller Based on URC

摘要:

当前大多数模糊系统的推理机都是以交规则的形式出现,随着输入的增加,规则的数目将呈指数增长,出现了规则组合爆炸的问题。采用并规则设计的一种模糊PID控制器,解决了规则爆炸的问题,同时改善了系统的动态性能和实时性。

Abstract:

Currently, most fuzzy logic systems are based on an intersection rule configuration (IRC). As antecedents are added to an IRC system, the number of fuzzy rules increase exponentially, giving rise to rule explosion. In this paper, a fuzzy PID controller based on union rule configuration (URC) was introduced, which avoided the rule explosion, and at the same time the system was better dynamic and real-time.
