Simulador didático para análise e controle de circuito de segunda ordem

Abstract

Second order systems are very important because they characterize the dynamics of many applications in the control area, such as servomechanisms, space vehicles, chemical processes, bioengineering, aircraft, ships, among others. Most control systems designs are based on second-order systems analysis. Based on this premise, the scope of this work was to develop a GUIDE in MATLAB®, with a second-order low-pass circuit, which aims to analyze its operation and compare the graphs and values obtained in different simulations, changing the values of the circuit components, allowing it to be classified into underdamped, critically damped or overdamped systems. With this, the objective of the work is to create a simulator of a control system that uses an electrical circuit as a system or plant and a software to perform control calculations. The user will have a graphical interface to operate and will be able to visualize graphs and generate commands in order to understand the transient responses and stability of a second-order system.
