摘要

分析了锅炉汽包水位变化的特点和内模控制(IMC)的特点

提出了基于IMC的汽包水位三冲量串级控制系统。该控制系统将蒸汽流量作为前馈信号

内环采用PID控制器

以克服给水流量、给水压力对汽包水位控制的干扰;外环采用IMC控制器

以克服蒸汽流量的干扰

并维持汽包水位恒定。将基于IMC汽包水位控制系统仿真结果与PID-PID汽包水位控制系统进行了对比

结果表明基于IMC汽包水位控制策略较PID-PID汽包水位控制策略响应更快速

稳态性能更好

具有良好的鲁棒性和抗干扰能力

同时验证了基于IMC的汽包水位三冲量串级控制系统的有效性。

Abstract

On the basis of analyzing the features of boiler drum water level variation and the internal model control(IMC)

an IMC-based three-impulse cascade control system for water level in boiler drum was proposed.This system regards steam flow rate as the feed-forward signal.In order to overcome the interference of water pressure and flow

the PID controller was adopted in the inner loop.The IMC was adopted in the outer loop to overcome the interference of steam flow rate and keep the water level constant.Results simulated by the IMC-based boiler drum water level control system were compared with that by the PID-PID boiler drum water level control system.The results indicated that

the IMC control system can response more rapidly

and had better steady state performance

stronger robustness and higher anti-interference ability.Furthermore

the effectiveness of the IMC-based three-impulse cascade control system for boiler drum water level control was verified.
