The mathematical model of quick-action non-linear system of phase frequency auto-tuning of frequency synthesizer with additional feedbacks to phase with dynamic controlled parameters to non-linear orders with expanded capture band was proposed in research. The non-linear differential fourth - order equation, which permits to analyze a work of improved system, was received.
