基于互联网的液压远程控制系统的协议选择和驱动方式研究

RESEARCH OF CHOICE OF PROTOCOL AND DRIVE METHODS IN TELECONTROL SYSTEM BASED ON INTERNET

针对基于互联网的远程控制系统存在的不确定性的信息延时问题,设计了具有补偿器和延时预测算法的系统结构。采用时间驱动的工作方式,并且选择UDP协议来实现系统软件。仿真研究表明,采用上述策略可以保证系统在互联网环境下的稳定性和比较好的动态性能,并且具有比较好的鲁棒性。

Compensators and forecast arithmetic in a telecontrol system based on Internet are designed to improve the system performance affected by uncertain Internet-induced time delay. UDP protocol and time-drive method are adopted to realize the telecontrol system. The simulation shows that the telecontrol system has better performance and robust.
