摘　　要：现有的控制方法节能效果差,调光等级高于固定值。为解决该问题,提出基于模糊自整定PID的绿色建筑室内照明自动控制方法。首先建立照明自动控制色温和光照强度的数学模型,调整和优化模型参数;然后运用模糊自整定PID控制器控制非线性系统,制定模糊自整定PID规则;最后根据色温偏差合理调整输出参数值设定,对模糊自整定PID控制器进行有效设计,根据光照强度的设定值与实际值之间的误差,运用PID控制器动态调整室内光强度,从而完成自动控制。结果表明,应用所提方法后,其调光等级均在24%~35%之间,等级值均低于固定模式,实现了良好的控制效果,节能效果理想。The existing control methods have poor energy-saving effect,and the dimming level is higher than the fixed value.In order to solve this problem,an automatic control method of green building indoor lighting based on fuzzy self-tuning PID is proposed.Firstly,the mathematical model of automatic control of color temperature and light intensity is established,and the parameters of the model are adjusted and optimized.Then the fuzzy self-tuning PID contrller is used to control the nonlinear system,and the fuzzy self-tuning PID rules are formulated.Finally,the output parameter setting is adjusted reasonably according to the color temperature deviation,and the fuzzy self-tuning PID controller is effectively designed.According to the error between the set value and the actual value of the light intensity,the PID controller is used to dynamically adjust the indoor light intensity,so as to complete the automatic control.The results show that after the application of the proposed method,the dimming levels are between 24%and 35%,and the level values are lower than the fixed mode,achieving good control effect and ideal energy saving results.
