Design and Robust Analysis of Internal Model Controllers for an Automatic Voltage Regulation System

摘要

In this article, two internal model correctors for alternator voltage regulation are presented. The amplitude of the voltage produced by alternators has a major influence on the stability of the electrical networks. The proposed internal model correctors are synthesized by the model inversion method; one uses a second-order model and the other one uses a first-order model. In order to evaluate the performance of the presented controllers in an automatic voltage regulation system, they have been compared to some proportional integral derivative and fuzzy logic correctors in the literature. The different stability margins allow validating the robustness of the proposed correctors. The results of this work are validated by simulations in the Matlab/Simulink environment.
