T-S fuzzy lighting control for an unknown arranged LED array

This paper presents T-S fuzzy lighting control of an unknown arranged LED (Light Emitting Diode) array for universal adaptable applications. In order to driving and lighting an unknown arranged LED array, a boost converter is applied to adjust the input voltage of the LED array. Based on the proposed T-S fuzzy model based control, exact LED lighting current control is achieved without searching the arrangement and turn-on voltage of the LED array. By solving linear matrix inequalities (LMIs), the T-S fuzzy LED lighting controller is guaranteed with asymptotic convergence and high robustness to uncertainty and disturbance. Moreover, the satisfactory performance is shown from experimental results.
