基于蛙跳PID算法的温室温湿度控制系统设计

随着农业智能化和信息化技术的发展,温室大棚环境因子的调控技术也成为研究的重点之一.为此,在深入分析温室环境特点与传统PID(proportionintegration differentiation,PID)控制技术不足的基础上,提出将蛙跳算法(shuffled frog leaping algorithm,SFLA)...

Design of Temperature and Humidity Control System for Greenhouse Based on Shuffled Frog Leaping PID Algorithm

With the development of agricultural intelligence and information technology,the regulation technology of environmental factors in greenhouses has become one of the research priorities.Based on the in-depth analysis of the characteristics of greenhouse environment and the insufficiency of traditional PID control technology,this paper proposes to combine the shuffled frog leaping algorithm with the traditional PID control algorithm to form the shuffled frog leaping PID algorithm and apply it to the research of temperature and humidity control in greenhouse.The experiment data shows that for the temperature control of the greenhouse,the error between the actual temperature and the optimal temperature is±0.6°at different sampling moments.And the maximum error is only 2.73%.In the humidity control,at 80%sampling time,the humidity parameters in the temperature chamber are within the optimal parameter range of 70%to 80%RH.
