Finite-Time Output Feedback Control for Electro-Hydraulic Servo Systems with Parameter Adaptation
Machines, 2021 Measurement noise, parametric uncertainties, and external disturbances broadly exist in electro-hydraulic servo systems, which terribly deteriorate the system control performance. To figure out this problem, a novel finite-time output feedback controller

Advanced Science, EarlyView.In this work, a bioinspired all‐in‐one underwater quality evaluation metamaterial, combining sound attenuation, diffuse reflection, and mechanical robustness, is proposed based on jumping spider locomotion and human skeletal biomechanics. Meanwhile, a CNN‑driven quality evaluation framework is established for theoretically dimension‐reduced ...

Multi‐scale Optimization on Interfacial Evaporative Cooling for Photovoltaic Performance Enhancement
Advanced Science, EarlyView.This study presents a passive siphon‐driven interfacial evaporative cooling technology for photovoltaics. A multiscale multiphysics model is developed and validated experimentally. Results show that optimizing installation parameters reduces operating temperature by up to 22.3 °C and boosts power efficiency by 8.9%, offering a practical pathway for ...

Frequency Characteristics of Electro-hydraulic Vibrator
Journal of UOEH, 2002 Frequency characteristics of an electro-hydraulic vibrator were measured using two kinds of test signals. First, sine signals had theoretically 1.0 m/s2 (root-mean-square) in the frequency range from 1 to 16 Hz at single axis. The frequency characteristics were flat from 1 to 12 Hz, but 14, 16 Hz was considerably poor.
