Abstract

Currently, one of the main focuses of any company or industry is the constant improvement of the performance, cost and quality of internal systems. Thus, automation is part of this improvement process and has become something indispensable nowadays. Automation can solve many problems as well as offer innovative proposals. Control system is a technology dedicated achieve this type of automation, one of the most used controllers in the industry is the PID controller, as it is a simple control with easy application and cost efficient. Proportional, Integral and Derivative (PID) control comes from the sum of the transfer functions of each individual control. The PID control will be responsible for controlling the system’s response, comparing the value of the desired voltage and the output voltage, applying a compensating system if necessary. The system chosen to apply a PID control is the DC-DC (direct Current to direct Current) buck converter, which is a voltage lowering circuit, where this reduction occurs due to the switching circuit. This converter is applied to various electronic circuits of our daily routine, such as power supplies for portable devices (cell phones, tablets, laptops and others). This project proposes to apply a PID controller in a Buck DC-DC converter, aiming to improve the output control and validate the knowledge acquired during the course.
