Design and research of High-power LED driver power supply based on Optimized PID algorithm
High-power LED illumination system has high requirements on the LED driver power supply including conversion efficiency, dimming efficient? and constant-currency accuracy. In this ptper, the design is on the bask of fly-back LED driver by SSL2101 and makes use of feedback and control theory of control system, hardware works in the closed-loop statejfeanwkile, we adopt genetic algorithm and direct search strategy to optimize PID parameters In the software design, the optimized PID algorithm can control the power better, aid closed-loop control In the software is reached. We will achieve precise control of output current and improve the output current stability, had opacity and conversion efficiency of the current source.
