摘要
开展了供气系统质量流量(简称流量)和压力的控制方案研究,提出采用多元线性回归预测和自适应比例调节的改进控制方法,对实验台各流路的电动阀门集成控制。设计一台测量控制系统操作台,采用西门子programmable logic controller(PLC)作为主控制器,可实现对46台电动阀门的自动控制,并且保留远程手动控制功能。该控制方式可根据不同电动阀门调节速度改变增加幅度,使得阀门调节更加平顺。基于实验台的管路情况,该控制方式相较于常规proportion integral differential(PID)控制,实验台各气路压力和流量超调量减少20%以上,调节时间缩短40 s以上,对于大流量工况,稳态性能可提高2%以上。
The mass flow rate and pressure control scheme of the gas supply system was studied,and the improved control method of using multiple linear regression prediction and adaptive proportional regulation was put forward to integrate the control of the electric valve of each flow path of the experimental platform.The design of a measuring control system operation table,using Siemens programmable logic controller(PLC)as the main controller,can realize automatic control of 46 electric valves,and retain the remote manual control function.The control mode can be adjusted according to different electric valve speed change/increase amplitude,making the valve adjustment more smooth.Based on the pipeline condition of the experimental platform,compared with the conventional proportion integral differential(PID)control,the control mode can reduce the overshooting of the pressure and mass flow rate of each gas path of the experimental platform by more than 20%,shorten the adjustment time by more than 40 s,and improve the steady-state performance by more than 2%for the large mass flow rate condition.
