摘要
单边直线感应电机(Single-sided Linear Induction Motors,SLIMs)作为中低速磁悬浮列车的驱动装置,其推力和法向力的优良控制特性以及抗干扰能力,对于列车的牵引及悬浮系统稳定高效运行极为重要。通过建立SLIM的最大加速度变电流跟踪控制模型,在加/减速区,控制SLIM以恒定最大加速度运行;在稳速区,为充分利用电机的容量,控制SLIM恒功率运行。实验验证了所提控制算法的有效性,不仅能有效研究SLIM推力特性,还能为探索磁悬浮的高效动态控制方法提供参考。
On the premise of constant slip-frequency, an approach of variant current with maximum acceleration is proposed to achieve high efficiency control of Single-sided Linear Induction Motors （SLIMs）. By regulating current, the thrust is kept with positive or negative to minimize time consumption in acceleration or deceleration sections, respectively, and zero value to bring SLIM into constant power running status in stability sections. Validity of the proposed algorithm is verified by experimental results, and this approach may have some implement value in maglev transportation control.
