过程控制系统的实时性分析

Analysis for Teal-Time Response in process Control System

实时性是过程控制系统的重要技术指标之一，本文以计算机控制系统为目标，分析了系统的实时响应能力，从数字模型出发，论述了实时响应与系统负载的关系。文章还进一步探讨了系统的优先级对实时性的影响。

Real-time response is one of the most important performance in process control system.Here,the response time of computer-based process control system is analysed.This paper discribes thebehaviour of real-time system,points ouf the relationship between real-time response and system work-load.Further,the effect of system priority on response time is also discussed.
