摘要

对控制系统微分环节使用过程中容易产生高频干扰现象进行了分析

提出了一种改进微分环节的控制策略

该控制策略使控制系统具有较好的频率特性。采用改进型微分环节对某超临界600 MW机组过热蒸汽温度控制系统进行了优化。结果表明

优化后的控制系统较原控制系统具有更加优良的调节品质。

Abstract

The high-frequency interference phenomenon easily occurred in application process of the differential link

hence

a new control strategy based on improved differential link has been put forward.The new control strategy can make the control system to have a better frequency behavior.By using the improved differential link

the superheated steam temperature control system of a supercritical 600 MW unit has been optimized.Result shows that the said control system after optimization has even better regulating quality than that of the original control system.
