Abstract :
A phase locked loop based system that tracks the resonance frequency of a series RLC circuit is investigated. Assuming that the RLC circuit parameters are slowly and time-varying, a linear time-invariant model that accurately predicts the performance of the system is developed. The results are illustrated by examples.
