摘要:为实现异步电机的高性能控制,提出了一种基于全分数阶P13p控制器的矢量控制系统设
计方法。根据分数阶控制器的数学特征,确定矢量控制系统中分数阶电流环控制器和分数阶电压
环控制器的形式;根据相位裕量、幅值及增益鲁棒性准则求出分数阶控制器的参数;在数值仿真中,
采用Oustaloup递归滤波器来实现分数阶算子的近似和有理化,对比了同样设计标准下整数阶控
制器和分数阶控制器在横转速、转速变化和负载突变下的动态性能。对所提控制方法进行了实验
验证,结果表明:相较于采用整数阶PID控制器系统,采用电流转速双闭环全分数阶P13驴控制器
系统的跟随性能和抗扰性能更优,使用分数阶的矢量控制系统能使阶跃响应的超调量和调节时间
分别下降24.84%和7.35%,在输入变化的系统中分数阶的动态降落为整数阶的22.5%。研究结
果表明,所提分数阶控制器的设计方法可用于异步电机高性能矢量控制系统。
