Prototipado rápido de control no lineal aplicado a convertidores conmutados de corriente continua de orden cuadrático

Abstract

This document presents a rapid control prototyping methodology to apply the disciplinary concept in the industrial field. Nonlinear control in quadratic-order DC-DC is used to reduce material and electronic device costs, as well as to enhance power quality in the system's response. The study begins with two types of switched quadratic converters. On one hand, the quadratic Boost type undergoes a dynamic analysis starting from its model and leading to the characterization of its behavior, including the procedure for calculating commercial-type elements, which involves the construction and design of its formal plant for behavioral research. Similarly, the quadratic Reductor type is also characterized based on a model, whose functionality is validated in an experimental physical plant to create a functional model ranging from 380V to 48V up to 500W. This is achieved using the dSPACE CP1103 rapid prototyping tool to implement the development of Model in the Loop (MIL), Software in the Loop (SIL), and Hardware in the Loop (HIL) with real-time simulation via Real-time Simulation (RTS). Furthermore, modern robust control techniques are employed, such as sliding mode control and passivity-based control, which are compared with classical control through a PID (Proportional-Integral-Derivative) arrangement established through optimization algorithms. This is done to propose a general framework for the desired response to parameter stability in the presence of disturbances. Finally, a results analysis is conducted based on performance indices, including response time, signal accuracy, system stability, and resource utilization efficiency.
