摘要
针对农业生产及温室中湿度控制非线性、延时性及无法建立数学模型等特点,提出了一款基于模糊控制的智能湿度仪。同时,根据湿度控制特定的设计需求,以黄瓜为例设计了一款模糊控制器,总结了数据和专家经验,得出合理的模糊规则。在MATLAB上进行了模糊控制的效果评估,以检测其规则及控制效果,并使用MAT-LAB的Simulink工具箱建立系统的动态模型对系统进行仿真。仿真结果表明,基于模糊控制的智能湿度仪具有良好的鲁棒性和动态性较好,具有较高的推广应用价值和农业生产价值。
This paper was focused on nonlinear,delay and uncertainty characteristics of the humidity control,and proposed intelligent hygronom based on fuzzy control.The design was not only further study of fuzzy rules but defuzzification by the minimum and maximum method and simulation study by MATLAB to test its rules and control effect.The simulation results was shown intelligent hygronom based on fuzzy control has good robustness,dynamic and widely application value.
