Nonsingular Integral Terminal Sliding Mode Control for Resonant Frequency Tracking of Electromagnetic Acoustic Transducers (EMATs) Based on Fixed-Time Strategy [PDF]
Micromachines, 2022 Resonant frequency tracking control of electromagnetic acoustic transducers (EMATs) remains a challenge in terms of drifting working frequency and reduced conversion efficiency caused by working environment changes.

Resonant Frequency Tracking Scheme for
IEEE Access, 2023 To achieve optimal system performance, it’s recommended to operate an LLC resonant converter at its resonant frequency. However, in mass production, the resonant parameters of different products can deviate significantly.

On the resonance frequencies of microbridges [PDF]
TRANSDUCERS '91: 1991 International Conference on Solid-State Sensors and Actuators. Digest of Technical Papers, 2002 The authors present the exact analysis of the natural frequencies of transverse bending of flat clamped-clamped beams subject to an axial force. Extensions of this model are presented for several aspects of transversely vibrating microbridges for which this model falls short.

A New Method to Detect and Track the Resonance Frequency of Piezoelectric Transducers in Ultrasonic Power Supplies [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2021 In this paper, a new method is developed to detect and track the resonance frequency of ultrasonic transducers. In order to have an acceptable performance of transducers, power supplies should be able to detect and track the resonance frequency ...

Negative-Frequency Resonant Radiation [PDF]
Physical Review Letters, 2012 Optical solitons or soliton-like states shed light to blue-shifted frequencies through a resonant emission process. We predict a mechanism by which a second propagating mode is generated. This mode, called negative resonant radiation originates from the coupling of the soliton mode to the negative frequency branch of the dispersion relation ...

Frequency Estimation for Grid-Tied Inverters Using Resonant Frequency Estimator
Energies, 2021 This paper introduces a new strategy of frequency estimation for grid-tied and stand-alone mode AC/DC power converters. Frequency stabilization is required, especially when operating in stand-alone mode with a Droop Control strategy, or in hybrid mode ...

Multi-frequency resonant clocks [PDF]
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015 Clock distribution networks consume a significant portion of total chip power in high-performance designs. Resonant clocks are one proposed method to lower this power in modern designs as well as a fewer required clock buffers. Recent resonant solutions are limited to optimal performance at one particular frequency which is problematic since dynamic ...

Spectral energy transfer of atmospheric gravity waves through sum and difference nonlinear interactions [PDF]
Annales Geophysicae, 2012 Nonlinear interactions of gravity waves are studied with a two-dimensional, fully nonlinear model. The energy exchanges among resonant and near-resonant triads are examined in order to understand the spectral energy transfer through interactions.
