Tracking the resonance frequency of a series RLC circuit using a phase locked loop

Abstract

Absfrucf-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 time-varying, a linear time-invariant model that accurately predicts the performance of the system is developed. The results are illustrated by examples.analysis method is developed. In Section 5, the results are illustrated. In Section 6, conclusions are given. PHASE LOCKED LOOPA phase locked loop [5], [6] is a feedback system that is composed of a phase comparator (PC), a low-pass filter (LPF) and a voltage controlled oscillator (VCO) as shown

A novel non-acoustic voiced speech sensor

“…While manual RF source tuning is possible, albeit inconvenient, in the laboratory environment, automatic RF source tuning will be necessary for field use of the sensor. One possible solution to this problem is the development of an automatic RF resonance tracking system using a phased-locked-loop (PLL) (Gokcek 2003). The bandwidth of the PLL should be designed to be below the minimum frequency of voiced speech.…”

Phase noise analysis of the Frequency Tracking Oscillator

“…The FTO is commonly used for MEMS vibrating sensors, its benefits have been demonstrated for QCM sensors [1,2], MEMS gyroscopes [3] and MEMS accelerometers [4], and the FTO also allows including self-test loops in the oscillator [5,6]. Studies have been undertaken to model the FTO in order to set properly the corrector parameters [7,8,9,10]. Although the frequency tracking ability of the FTO is now well known, its phase noise that determines the resolution of the sensors has not been studied, that is the goal of this paper.…”

Novel method for tracking the resonance frequency of RLC loads using extended kalman filter

“…In order to maximize power conversion efficiency, it is necessary to drive these loads at their resonance frequencies [1]- [6]. Element value changes due to temperature dependency, manufacturing variability and load variations is inevitable in these applications.…”

“…Ultrasonic motors, piezoelectric transducers, induction heating loads and certain loads for power inverters can be modeled as series RLC circuits [1]- [5]. In order to maximize power conversion efficiency, it is necessary to drive these loads at their resonance frequencies [1]- [6].…”

“…In each case, no mathematical analysis and design rules are offered exactly. Analytical control approach is investigated for an RLC load in [1]. The variation of the RLC element values are assumed slightly and a linear time-invariant model is extracted for mathematical analysis.…”
