Smart Illumination System Based on an Integrating Controller

The present project describes the design and development of a system that stabilizes light intensity in a specific area through an integrating controller. The controller is built with an Arduino Mega 2560, it uses a BH1750 light sensor that runs through an I2C communication and the final control element is a set of 100 LEDs which generates the light for the analyzed area. In order to design the control constants, a nonlinear mathematical plant model was developed, for this 166 experimental points of the system were analyzed in an Open-loop, through this a third degree polynomial expression was obtained, and used as reference. This project can also be used for educational purposes, it has been developed in a MatLab environment, in which you can monitor the control signals and manipulate the operating point of the plant.
