The invention discloses a lighting energy-saving control method based on a variable-amplitude gradient extremum search algorithm, which maintains the illuminance requirements through PID closed-loop control, and at the same time uses the variable-amplitude gradient extremum search algorithm to continuously iterate and quickly find the energy consumption of the lighting system The lowest value, and keep the lowest value stable output; In the variable amplitude gradient extreme value search algorithm, a positive signal is introduced to change the amplitude of the disturbance, this variable first increases rapidly to ensure the accuracy of the algorithm, and then decreases , which shortens the time required for algorithm search, and at the same time adds a self-closed loop system, which can make the output more stable and fast by adjusting the parameters. By adopting the invention, the speed and accuracy of the gradient extremum search algorithm can be improved, thereby improving the overall performance of the lighting energy-saving control method.
Description
Technical field [0001] The invention belongs to the technical field of lighting control, and more specifically, relates to a lighting energy-saving control method based on a variable amplitude gradient extreme search algorithm. Background technique [0002] According to statistics, China's building energy consumption accounts for more than 35% of the total energy consumption of the whole society, and lighting energy consumption accounts for more than 25% of building energy consumption. How to reduce energy consumption has become the primary problem facing all walks of life. The present invention further reduces energy consumption while meeting the illumination requirements. [0003] The traditional lighting system can only be controlled by turning on and off, while the existing lighting control system can meet the needs of users by adjusting the brightness of the lamp, achieving certain energy saving, but the control method is more complicated and energy-saving not effectively.
