This paper proposes a Phase Locked Loop algorithm for three-phase distorted systems. For the Phase Locked Loop it is deduced a mathematical model to design the three different control solutions implemented: a PI, a PID and a novel fractional PI. The damping ratio, the time response and the phase error of the phase tracking system are the criteria to design the controllers. The performance of the three systems is analyzed by connecting inputs with imbalance, harmonics and phase and/or frequency variations. An Autoadjustable Synchronous Reference Frame application is developed to test the Phase Locked Loop by simulation and experimentally through xPCTarget. A comparison of some parameters of the system such as phase margin, settling time, THD and phase error is carried out for each controller.

W artykule zaproponowano algorytm pętli synchronizacji fazy dla odkształconych przebiegów w systemach trójfazowych. Sformułowano model matematyczny pętli fazowej służący opracowaniu rozwiązań z regulatorami PI, PID oraz nowatorskim, ułamkowym PI. Kryteriami projektowymi są poziom tłumienia, czas odpowiedzi i błąd fazowy układu śledzenia. Właściwości trzech systemów zostały zbadane przy zastosowaniu sygnałów niesymetrycznych, odkształconych oraz z wahaniami fazy i częstotliwości. Pętle fazowe testowane były symulacyjnie i doświadczalnie poprzez xPCTarget przy użyciu aplikacji Autoadjustable Synchronous Reference Frame. Przedstawiono porównanie wybranych parametrów takich jak marines fazy, czas synchronizacji, THD i błąd fazowy.
