In this study,a double fuzzy control algorithm for automatic light locking of intelligent curtain system is designed on the basis of traditional PID regulation,aiming at the requirements of anti-interference and robustness of intelligent curtain control system in practical use.Using the double fuzzy control to the input voltage and output speed of the DC motor,the system can automatically,steadily,and quickly control the curtain opening and closing according to the indoor light intensity,and then complete the accurate adjustment of indoor light intensity,and realize the light locking function of the intelligent curtain system.The mathematical model of the system was established by Simulink and fuzzy controller module in MATLAB to verify the feasibility of the double fuzzy control algorithm.The experimental results show that the algorithm can adjust the speed and steer the motor in real time according to the change of regional light conditions,and it has the characteristics of short adjustment time,high sensitivity,and high precision,and can achieve the optimal control of adjusting the indoor light intensity through curtains.
