摘要
研究了一种可实现模糊PID控制的双容液位控制系统,此系统利用XLPC-III过程控制实验装置和虚拟仪器实现了PID控制器参数的在线自整定和直观实验效果,同时又增强系统的抗扰能力,从而改变了传统双溶液位控制中的非线性、参数时变、工控机作为下位机特点,降低了传统双容液位控制系统开发难度、缩减了系统开发时间.实验对液位从70mm上升到125mm稳定范围进行分析,结果表明,此系统具有良好的动态品质.
This paper studies a Two-Tank Liquid-level Control System using fuzzy PID algorithm.This system realizes the on-line self-adjusting of PID control parameters and visual experiment results.At the same time the anti-interference of the system is improved.As a result,it changes the non-linearity in controlling of the traditional two-tank liquid-level system,time-varying parameters,the characteristics of Industrial Personal Computer as lower computer,reduces the difficulties of developing traditional two-tank liquid-level system,and shortens the developing time of the system.Through experiments on stability range of liquid level from 70mm to 125mm,the experimental results show that the system has excellent dynamic quality.
