摘　　要：永磁直线同步电动机(PMLSM)运行时电流谐波会影响控制精度和鲁棒性,此处提出一种基于分数阶的比例积分矢量谐振控制(PI-FOVRC)方法。比例积分矢量谐振控制器可少电流谐波,但PMLSM运行时有参数变化现象,导致矢量谐振控制(VRC)增益降低,谐波增大。为此,在VRC中引入分数阶,设计PI-FOVRC,降低增益,减少谐波。理论分析和实验结果表明,所设计的PI-FOVRC方法提高了系统控制精度,减少了电流谐波,提高了系统鲁棒性。The current harmonics of permanent magnet linear synchronous motor(PMLSM)will affect the control accuracy and robustness,a proportional integral vector resonance control method based on fractional order(PI-FOVRC)is proposed.The proportional integral vector resonance controller can reduce the current harmonics,but there is a parameter change phenomenon during PMLSM,resulting in a decrease in the gain of the vector resonance control(VRC)and an increase in harmonics.For this purpose,fractional orders are introduced into VRC,and PI-FOVRC is designed to reduce gain and harmonics.Theoretical analyses and experimental results show that the PI-FOVRC method is designed to improves the system control accuracy,reduces current harmonics,and improves system robustness.
