预测控制在锅炉燃烧系统中的应用

摘要

Predictive control is a new computer algorithm developed inrecent years.This paper starts from inner model and inner model controller,and has derived the time delay compensation principle of Smith predictive control and inner model control structure design of Smith predictor.Using the scatter control system of INFI-90 and Smith series regulation system realizes the predictive control for main steam pressure.%预测控制是近年发展起来的一类新型计算机控制算法，该文以内部模型与内模控制器出发，推导出Smith预测控制的时延补偿原理和Smith预测器内模控制结构设计，然后结合工业锅炉燃烧系统中主汽压力控制，利用INFI-90分散控制系统的Smith预测控制器及其它控件构成一个带前馈的串级调节系统，实现了主汽压力的预测控制。
