摘要
根据模糊匹配规则,利用MATLAB/Simulink软件设计了模糊可调分数阶PIλDμ控制器模型,分别与整数阶PI、分数阶PI~λD~μ控制器模型对无刷直流电动机转速控制效果进行了对比.结果表明:模糊分数阶PI~λD~μ控制器响应更快速、更精准,抗负载扰动能力更强.
According to the fuzzy matching rules, the fuzzy adjustable fractional-order controller model was designed using MATLAB/Simulink software. The effect comparisons of BLDCM(Brushless Direct Current Motor) speed controllers applied with integer-order PI and fractional-order PID algorithms were performed respectively. The results showed that the fuzzy fractional-order controller has faster response speed, more accurate control performance and better capacity of resisting load disturbance.
