基于光照的温室加热系统模糊PID控制

为了给冬季作物提供适宜的生长环境,综合考虑自然光和节能因素,提出了一种基于光照的温室加热系统模糊PID控制方法。首先,根据温室的光照强度和天气预报信息,建立温室内温度的设定模型;然后,结合常规PID控制算法简单、鲁棒性好及可靠性的优点,采用模糊控制思想对PID控制参数进行调整,使控制系统可以依据不同的偏差相应地调整;最后,使用Mat Lab中Simulink对控制算法进行了仿真试验。结果表明:该控制方法稳定性高、动态响应好、抗干扰能力强,为提高温室生产的经济效益提供了理论依据。

Fuzzy PID Control of Greenhouse Winter Heating System Based on Illumination

In order to provide a suitable growth environment for winter crop , a novel fuzzy PID control method for green-house heating system based on light was proposed by taking the natural light and energy -saving factors into consideration . Firstly , the temperature setting model for greenhouse was established according to the light intensity in greenhouse and weather information .Owing to the advantages of conventional PID control algorithm , which is simple , robustness and reli-ability , this paper then adjusted PID control parameters by combining with PID control .This kind of control system could be adjusted depending on the deviation .Finally , Simulink in Matlab was applied to do control algorithm simulation .Simu-lation results showed that the proposed control method was high stability , good dynamic response and strong anti-jamming capability , which could provide a theoretical basis for improving the economic benefits of greenhouse production .
