Abstract


The new methods of acceleration harmonic signal frequency tracking based on estimates ofinstantaneous frequency and phase, are proposed and investigated. Better efficiency of new systems e.g. quicker transient process and bigger frequency range is proved in comparison with conventional system of frequency synchronization

Keywords
