摘要
提出了一种无刷直流电机的 F uzzy-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 ,若仅采用传统的 PI调节器 ,则难以克服系统超调和短时振荡问题。采用复合 F uzzy-PI的控制方法 ,并且采用自适应的权值修正方法来修正 F uzzy回路与 PI回路的连接权值。最后 ,在 Matlab与 Sim ulink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 novel Fuzzy-PI controller is proposed for controlling the speed of BLDCM in high-performance drives environment. In such environment,if PI controller is only used,there must be over-regulating and instantaneous oscillation. In this paper,a multiple Fuzzy-PI system is used,and a adaptive weight updating algorithm is proposed in this paper to revise the linking weights between Fuzzy and PI circuits. The result of this control method is satisfied in simulation based matlab and simulink. So,this method help to reduce the over-regulating and eliminate oscillation.
