电动平台实时系统的设计

Design on the Electric Platform Real-time System

针对六自由度电动平台系统的实时性差的问题,文章给出了一种新的采用Windows+RTX的全软件实时控制系统的方法。针对实验室运动平台要求,为系统设计了整体控制方案,采用Ether-CAT环形以太网络连接模式实现数据高效传输。对建立的电动平台系统进行延迟及跟踪实验,实验结果表明该设计方案大大提高了系统的实时性能及跟踪精度,具有很好的工程实用价值。

For problem of poor real-time in six degrees of freedom motorized platform system, this paper presents a new method using Windows ＋ RTX software real-time control system. In response to the motion platform requirements, design the overall control scheme for the system, and using EtherCAT ring Ethernet connection mode to achieve the efficient transmission of the data. To the the electric platform system design the delay and tracking experiment, results show that the design greatly improved the system＇s real-time performance and tracking accuracy, and with good engineering practical value.
