Projeto e implementação de um conversor cc-cc boost com controle Proporcional-Integrativo-Derivativo (PID)

Abstract

This work proposes the analysis of PID controllers developed using a mathematical tool, pidtool, to define the controller parameters for controlling a boost converter. The boost converter is designed to ensure a 15V output with a fixed 5V input. Experiments without the use of controllers are performed to confirm the voltage level increase. When the controllers are implemented, an 8V setpoint is defined for the output to protect the connected components in case of potential failures, considering it is a prototype. Computational simulations and practical experiments are conducted using the proposed converter parameters to compare the step response of the proposed controllers. Finally, a discussion is held on the collected data, the applicability of the matlab pidtool in designing PI, PD, and PID controllers, and a brief discussion on future studies regarding the impact of different hardware types on control.
