摘要
综述了直线感应电机在轨道交通中的应用情况和相应的控制技术,从直线感应电机相比于与旋转感应电机的特殊性出发,详细论述了造成特殊性的原因以及对列车运行和控制的影响,并概述解决方式和研究方向。针对轮轨式和磁悬浮式的牵引控制系统,介绍了两者的控制策略,详细阐述了针对直线感应电机的特殊控制方法。论述了在直线感应电机牵引系统中的几种新型控制策略和未来的研究方向。
The application in the linear induction motor for the rail transit and the corresponding control technology,and the current research status in control technology were summarized.Starting from the particularity of linear induction motors compared with rotary induction motors.The reasons for the particularities and their influence on operation and control,and outlines solutions were discussed.For wheel-rail and magnetic levitation traction control systems,the two control strategies were introduced,and the special control structure for linear induction motors was elaborated.Several new control strategies and future research directions in the linear induction motor traction system were discussed.
