Proportional-Derivative Plus Integral Controller Tuning for Led Lighting Based on the Mathematical Model

Abstract

The depletion of energy resources have made saving energy a challenge in recent decades. One of the main components of energy consumption is lighting, it represents up to 20% of total energy consumption in the world; the largest amount consumed in residential and commercial buildings. Led technology, due to its characteristics of long life, high efficiency, low consumption and dimming capacity, has become an alternative to illuminate spaces. This work proposes a control scheme for LED lamp lighting with a double control loop, proportional- derivative in the internal loop and integral in the external one, based on the mathematical model in the absence of external lighting. In addition, the tuning strategy for the controller gains is proposed based on the design parameters of the standard second-order system. Through simulation it is shown that the tuning of the control strategy is adequate.
