基于模糊PID控制的大棚温控系统设计

Design of Greenhouse Temperature Control System Based on Fuzzy PID Control

随着我国农业的发展,人们对反季节作物的需求越来越高,大棚产业逐渐发展成熟.文章建立了基于模糊PID控制的大棚温控系统,分析了大棚中温度在调控器作用下的变化情况,给出了其数学模型,描述了模糊PID控制的原理,设计了基于模糊PID控制的大棚温控系统,并在Simulink中搭建了仿真模型.仿真结果显示,基于模糊PID控制的大棚温控系统可快速、有效地调控大棚中的温度.与传统PID控制相比,该系统控制效果更好,可大幅缩短控制时间.

With the development of agriculture in Our country,people's demand for off-season crops is getting higher and higher,and the development of greenhouses is gradually put on the agenda.This paper establishes a greenhouse temperature control system based on fuzzy PID control.Firstly,the change of the regulator and the mathematical model are presented.Secondly,the principle of fuzzy PID control is described,and the greenhouse temperature control system based on fuzzy PID control is designed.A simulation model is built in Simulink.The simulation results show that the greenhouse temperature control system based on fuzzy PID control can quickly and effectively control the temperature in the greenhouse.Compared with the traditional PID control,the control effect is better and the control effect can greatly shorten the control time.
