摘　　要：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)与传统的PID控制算法融合,形成蛙跳PID算法,并应用于温室大棚的温湿度控制研究。试验结果表明:对于温室的温度控制方面,在不同的采样时刻,实际温度与最佳温度的误差在±0.6°之间,最大误差仅为2.73%;在湿度调控方面,在80%的采样时刻,温室内的湿度参数都处在最佳的参数范围70%~80%RH内。本文设计的蛙跳PID控制系统控制精度高,温湿度调控误差小,实际应用效果好。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.
