单容水箱液位模糊控制系统的设计与研究

针对传统工业单容水箱液位控制过程中存在的稳定性差、响应慢等问题，提出了一种模糊控制方法对液位进行控制。首先根据单容水箱液位的控制要求设计了模糊控制器．然后搭建了基于远程数据采集模块的计算机控制系统．最后在VB环境下．设计了单容水箱液位监控人机界面进行液位控制。实验结果表明．在单容液位过程控制系统中．采用模糊控制与闭环P1D控制相比．稳定性更好、响应速度更快。液位控制性能明显提高。

Design and Research of Fuzzy Control System for Single Tank Liquid Level

To the problems of poor stability and slow response in the traditional industrial single water tank control, this paper presents a fuzzy control method to control the liquid level. Firstly, a fuzzy controller is designed based on the single-tank water level control requirements, and then a computer control system based on remote data acquisition modules is built, finally in the VB environment, the single tank water level monitoring human-machine interface is designed to control the liquid level. The experimental results show that the fuzzy control system is stable in performance and rapid in response in the single tank liquid level process control, compared with dosed-loop PID control, and the liquid level control performance is improved obviously.
