Basic Concepts of a Phase-Locked Loop Control System

Abstract

Phase-locked loop (PLL) is one of the main components of
modern electronic design and has been around for a considerable number
of years. It is a technique that has greatly contributed to the technological advancement of communications and control systems. This paper
presents a phase-locked loop tutorial based on a control system, it gives
a concise review of basic concepts, the different types of PLLs, linear
analysis approaches of analog systems PLL is discussed, furthermore the
theoretical analysis of the steady-state error in detail is presented, and its
simulations of different phase offset values in C program are presented,
and show how the response of the loop changes.
