| Summary: | 碩士 === 中原大學 === 電機工程研究所 === 98 === The purpose of this thesis is to design a T-S fuzzy dimming controller for an unknown arranged LED array. In the past, the LED driving controller design only focuses on efficiency improvement, so that we should know the composition of the LED array, i.e., the application is limited. To solve this problem, we will use the DC/DC boost circuit as a driver circuit and design a T-S fuzzy dimming controller. The advantage of this approach is fast convergence and high stability. In order to verify the validity of the proposed control method, we apply digital signal processing card (DSP card) to implement the controller. Finally, the DSP based controller is replaced by the PSoC CY8C29466 chip controller, so that the proposed T-S fuzzy dimming controller has more worthwhile.
