After an introduction to PLL and PLL based systems, an analysis of the methods to improve the performance of such systems aimed to the Harmonic Analysis is presented. Among these methods an approach to using the Genetic Algorithm is shown with its results.
PLL principles system and its applications in harmonic analysis are firstly discussed and then integrated presenting methods to increase the PLL-based instrumentation efficiency. A comparison between the performance of systems before and after the application of these methods are shown to validate the efficiency o f the proposed methods.
