Multi-Parameter Control Simulation of Indoor Environmental Lights under Point Light Source Environment

In order to improve the adaptive performance of indoor lighting,the lighting parameters should be controlled comprehensively.In this article,a method to control multi-parameter indoor lighting in point light source environment based on fuzzy PID was presented.Based on the adaptive learning method of dynamic elements,a constraint parameter model of indoor lighting control was constructed.Under the constraint of model parameters,the brightness and the angle of indoor lighting were adjusted by coupling adjustment of multiple degrees of freedom.Moreover,fuzzy PID control method was used to fuse the luminance information and output information.The fuzzy PID control law was established to realize multi-parameter fusion adjustment and control of indoor lighting parameters such as color,light intensity,beam angle and beam diffraction characteristics.Simulation results show that the proposed method can effectively improve the effect of color fusion by controlling indoor lighting parameters.Meanwhile,this method has better adaptive performance,stronger control law performance and higher applicability.
