Vector control of induction motor based on fractional-order intelligent-integral speed controller

为进一步改善基于矢量控制的异步电动机调速系统的动、静态性能,并提高其鲁棒性,将改进的分数阶智能积分(IPIλ)控制器应用于矢量控制系统的速度调节器。改进的分数阶智能积分根据偏差的变化将分数阶积分和比例相结合,通过与普通PI和FOPI控制器相比较,发现IPIλ具有更好的控制效果。仿真试验表明,分数阶智能积分控制器不仅能够快速、精确地跟踪给定速度,而且对负载扰动及参数变化具有更好的抗扰性和较强的鲁棒性。

To improve dynamic and static performances and robustness of the induction motor speed control system based on vector control,an improved fractional-order intelligent proportional integral(IPIλ)controller was applied to the speed controller of the vector control system,which combined the intelligent fractional integral with the proportion according to the variation of deviation.Compared with proportional integral(PI)and fractional-order proportional integral(FOPI)controllers,the IPIλcontroller achieved better control performance.The stimulation results indicate that the IPIλcontroller can not only track the given speed quickly and accurately,but also have better anti-interference and robustness for load and parameters variations.
