Modelagem e controle de conversores CC-CC via estratégias de controle clássicas

Abstract

The use of renewable energy has enabled new ways of generating electricity by means of photovoltaic energy, wind energy, among others.In order to improve the voltage regulation, DC-DC converters are used.Modeling Buck converters and linearization around an operating point ensures proper operation of the drive as a voltage regulator or a power regulator.To guarantee the operation of these converters as regulators, controllers are designed to ensure that the permanent and transient regime specifications for the converter operating at the operating point.In this work the controller designed is the PID structure being designed by two classical methodologies: Pole Placement and Root Locus.Once the controllers were designed, the performance of the controller acting with the system outside the operating point was verified.
