提出了一种无刷直流电机的 Fuzzy-PI 转速调节器的设计方法。在无刷直流电机的高性能速度跟踪中,采用传统的 PI调节器,则难以克服系统超调和短时振荡问题。采用复合 Fuzzy-PI 的控制方法,并且采用自适应的权值修正方法来修正Fuzzy 回路与 PI 回路的连接权值。最后,在 MatIab 与 SimuIink 下进行了仿真,结果表明,运用这种设计方法很好地抑制了超调和振荡。%In this paper,a noveI Fuzzy-PI controI er is proposed for controI ing the speed of BLDCM in high-performance drives environment.In such environment,if PI controI er is onIy used,there must be over reguIating and instantaneous osciI ation.In this paper,a muItipIe Fuzzy-PI system is used,and an adaptive weight updating aIgorithm is proposed to revise the Iinking weights between Fuzzy and PI circuits.
