Control system design of traction transducer for Maglev Train

磁悬浮列车采用VVVF变频器控制感应直线电机的运行,对牵引变频器控制系统的可靠性要求较高。文章介绍了一种牵引变频器控制系统的设计方案,它兼顾了软件的灵活性和硬件的实时性,在软件和硬件之间合理分配任务,提高了系统的可靠性。

The Maglev Train adopts VVVF transducer to control Linear Inductor Motor to realize traction and brake, and it requires the control system of transducer to be highly reliable. Taking the characteristics of software and hardware into consideration simultaneously, the design scheme presented in this paper distributes tasks between them reasonably. As a result, the reliability of control system is improved.
