Synthesis of Phase-locked Loop System Structure with Adaptation Based on Combined-maximum Principle

Abstract

The synthesis of the structure of the phase-locked loop system is performed based on the generalized power function maximum condition. The system effectiveness in the lock-on mode is studied via numerical simulation. Compared to the classical one phase-locked loop system with RC-filter this solution is characterized by the higher stability with respect to external influences and by reduced phase error in the steady-state.
