Modelagem, projeto, simulação e implementação de um controlador digital aplicado a uma estação de solda com temperatura variável

Abstract

This Course Conclusion Work the Modeling, Design, Simulation, and Implementation of a Digital Controller Applied to a Soldering Station with Variable Temperature are proposed. Considering that one of the main parameters in soldering components on printed circuit boards is the temperature of the material to be melted. In this context, precise control of the temperature of the tool used for soldering becomes attractive. This work was developed in the following manner: (i) mathematical modeling of the soldering station; (ii) Design of the digital temperature controller; (iii) Simulation of the system in open loop; (iv) Physical implementation of the control system; (v) Analysis of simulated and experimental results; and (vi) Validation of the control system. Through this document, the behavior of the soldering station was observed through modeling, design, and simulation. During the practical development stage of the system, efforts were made to meet the project’s performance specifications. Challenges were encountered between theory and practical implementation, such as nonlinearities and problems with control system saturation, resulting in wind-up of the control action. The results were better for the proposed control system that used a PID controller, compared to On-Off methods and the open-loop response of the system, with a 163 % improvement in the stabilization time parameter and virtually zero steady-state error.
