Modelos de máquinas síncronas para projetos de sinais estabilizadores usando-se teoria de controle ótimo.

Abstract

This work presents a comparative analysis between the models of synchronous machines used in projects or stabilizing signals based on the optimal control theory. This comparison takes into account the feasibility of the stabilizers in a realistic implementation in which only some variables are physically accessible for the measurement. In this research for illustrative purposes, it is considered a system consisting of three machines and an infinite bar. Based on the optimal state feedback, several control signals are projected from the linearized model of 7th, 6th, 4th and 3rd order for synchronous machine / voltage regulator. Following are tests of implementation of the various controllers for purposes of comparison and obtaining conclusive results.
