Abstract
In this paper, the constant current controller will be designed to regulate the driving current of the power LEDs. The adaptive controller will also be designed to estimate the varying parameters of the power LEDs with the driving circuits. The mathematical model of the power LEDs driving system will be introduced to design the current controller. The buck type converter will also be presented to control the driving current of LEDs. The robustness of the proposed power LEDs system with adaptive control law will be experiment on the parameters variation.
