Low voltage ride-through strategy for a grid-forming converter with 3 times current overload based on adaptive virtual impedance

Frontiers in Energy Research
IntroductionDuring three-phase faults in power grids, existing low-voltage ride-through (LVRT) strategies are often constrained by the current withstand capability of converters, resulting in insufficient voltage support.

Virtual Quartz Crystal Microbalance: Bioinspired Resonant Frequency Tracking

Biomimetics, 2022
The reference acoustic properties of the quartz crystal used as a resonator are ensured by its high-quality factor (Q-factor). The microbalance of the quartz crystal (QCM) exploits the bulk acoustic properties of the quartz crystal.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

The Control of Tendon-Driven Dexterous Hands with Joint Simulation

Sensors, 2014
An adaptive impedance control algorithm for tendon-driven dexterous hands is presented. The main idea of this algorithm is to compensate the output of the classical impedance control by an offset that is a proportion-integration-differentiation (PID ...
