远程控制系统中随机时延的处理方法

A random time-delay processing method used in a telecontrol system

在基于因特网的远程控制系统中,为了解决因特网中随机时延问题,提出了一种适用于反馈通道的新方法。该方法在时间驱动的基础上引入了事件驱动,在远程计算机端,通过对网络时延导致的控制信息偏差进行补偿,最终使得反馈通道中随机时延的系统与反馈通道中固定时延的系统等效。

To solve the problem of random time delay in an internet-based telecontrol system, the paper proposes a new method which can be used in a feedback path. The method adopts an event-driven mode based on the time-driven mode. The random time delay can bring errors to control information, which can be compensated in a remote computer. The result is that the system of random time delay is equal to that of the fixed time delay in the feedback path.
