A novel active damping control based on grid-side current feedback for LCL-filter active power filter

open access: yesEnergy Reports, 2020
LCL filter is widely used in grid-connected converters for good harmonic mitigation performance. However, resonance poles of LCL filter challenge system stability, especially in a digital control system.

Review of Magnetorheological Damping Systems on a Seismic Building

open access: yesApplied Sciences, 2021
Building structures are vulnerable to the shocks caused by earthquakes. Buildings that have been destroyed by an earthquake are very detrimental in terms of material loss and mental trauma.

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome

open access: yesFEBS Letters, EarlyView.
In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...

A Capacitor-Current-Feedback Active Damping Control Strategy With Phase Lead Compensation for LCL-Type Grid-Connected Inverter

open access: yesIEEE Access
Capacitor-current-feedback (CCF) active damping is widely used to deal with the hazard of LCL filter resonance in the grid-connected inverter based on either phase lead or lag compensation, and the effect of active damping on open-loop of the control ...

Semi-Active System of Vehicle Vibration Damping

open access: yesApplied Sciences, 2021
This article discusses the vibration of a vehicle equipped with four semi-active dampers. The friction forces generated in these dampers have crucial influence on the intensity of the vehicle vibration.

PASSIVE DAMPING OF SPACECRAFT SANDWICH PANELS [PDF]

open access: yes, 2007
For reusable and expendable launch vehicles as well as for other spacecraft structural vibration loads are safety critical design drivers impacting mass and lifetime. Here, the improvement of reliability and safety, the reduction of mass, the extension

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A comparison of active, passive and hybrid damping treatments in structural design

open access: yes, 1996
The optimum design of structures are obtained for three different types of damping treatments, and the resulting designs are compared. The three types of damping treatments considered are constrained layer damping, active constrained layer damping, and ...

Control of the Weakly Damped System with the Embedded System Support

open access: yesAdvances in Electrical and Electronic Engineering, 2018
This paper deals with the experimental verification of the importance of embedded systems with an applied MEMS sensor in controlling weakly damped systems. The aim is to suppress actively residual oscillations.
