Phase-locked loop-less current controller for grid-connected photovoltaic systems
(Institution of Engineering and Technology, 2012-11)
A current controller suitable for three-phase photovoltaic systems is presented. The proposed controller ensures the injection of sinusoidal and balanced currents, with high immunity to both imbalances and harmonics present ...
Implementation Oriented Two-Sample Phase Locked Loop for Single-Phase PFCs
A low-resource-consuming digital implementation of the Two-Sample (2S) Phase Locked Loop (PLL)for application in low cost single-phase Power Factor Correction (PFC) converters is proposed. The design reduces the sampling ...
Phase-Locked Loop design applied to frequency-modulated atomic force microscope

Route to chaos in a third-order phase-locked loop network
(ELSEVIER SCIENCE BV, 2009)
Phase-locked loops (PLLs) are widely used in applications related to control systems and telecommunication networks. Here we show that a single-chain master-slave network of third-order PLLs can exhibit stationary, periodic ...
Comparative analysis of synchronization algorithms based on PLL, RDFT and Kalman Filter
(2007-12-01)
This paper discusses the main characteristics and presents a comparative analysis of three synchronization algorithms based respectively, on a Phase-Locked Loop, a Kalman Filter and a Discrete Fourier Transform. It will ...

Phase-Locked loops lock-in range in Frequency Modulated-Atomic Force Microscope nonlinear control system
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Since the mid 1980s the Atomic Force Microscope is one the most powerful tools to perform surface investigation, and since 1995 Non-Contact AFM achieved true atomic resolution. The Frequency-Modulated Atomic Force Microscope ...
