Control of ball mill storage pulverized coal system
摘要
火电厂中储式制粉系统钢球磨煤机(球磨机)为多变量耦合、大滞后及非线性复杂被控对象
传统采用的3套独立PID控制系统不具有自适应性和解耦性
故自动控制效果不理想。为此
以火电厂中储式制粉系统球磨机为对象
基于预测控制对其进行了控制研究
提出了球磨机控制方法和存在问题
给出了仿真模型
并对球磨机模型预测控制与常规PID控制进行仿真比较。结果表明
模型预测控制较常规PID控制
控制效果具有显著改善。
Abstract
Ball coal mill system is a complicated object with characteristics of multi-variety coupling
nonlinear and time-delay.The conventional independent three sets of PID controlling systems have no auto adaptability and decoupling ability
so it cannot work steadily for long term and the control effect is not good.By taking the thermal power plant's ball mill pulverizing control system as the research object
the ball mill pulverizing control system's control method and existing problems were investigated
from the view of predictive control.Moreover
the simulation model was established
and simulation comparison between model predictive control and PID control was carried out.The results show that the model predictive control can obtain fairly good results.
