基于PLC的消防水罐液位模糊控制系统

The Fuzzy Control System of Liquid Level in the Fire Water Tank Based on PLC

介绍了石油化工企业中消防水罐液位带修正因子的模糊控制系统。设计了一种混合型模糊控制器即开关式双模糊控制器,和传统PID调节器相比,带修正因子模糊控制系统超调量明显变小,系统调节时间显著缩短,系统的动态性能大大提高,控制效果明显改善,并且产生了较高的经济效益。因此该带修正因子模糊控制是一种理想的液位控制器。

The fuzzy control system with a correction factor for the fire water tank in petrochemical enterprises is introduced. A mixture type fuzzy controller, i.e. a switch type double fuzzy controller has been designed. To compare with the traditional PID modulator, the super adjustment quantity of the system with the correction factor has become small obviously; the system regulation time is reduced remarkably; the dynamic performance of the system is raised; control effect is improved; higher economic benefit has been achieved. So the fuzzy control system with the correction factor is a ideal liquid level controller.
