RISSampled Data Feedback-Feedforward Control of Structures with Time Delays
Publisher: American Society of Civil Engineers
Abstract: A sampled data control algorithm taking into account external excitations was developed for structural engineering applications. The structure was modeled as a continuous system controlled by a digital control system. In ...
Experimental Investigation on the Wake Characteristics and Aeromechanics of Dual Rotor Wind Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was carried out to investigate the aeromechanics and wake characteristics of dualrotor wind turbines (DRWTs) in either corotating or counterrotating configuration, in comparison to those of a conventional ...
Adaptive Feedback–Feedforward Control of Building Structures
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a combined feedback–feedforward control algorithm for reducing structural response of buildings to seismic excitations. The controller contains both feedback and feedforward components. The feedback ...
Positional Accuracy Improvement of an Industrial Robot Using Feedforward Compensation and Feedback Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Industrial robots play an important role in the transformation and upgrading of aviation manufacturing technology by their advantages of high flexibility, high efficiency, and low costs compared to the conventional ...
Structural Damage Diagnosis and Assessment under Seismic Excitations
Publisher: American Society of Civil Engineers
Abstract: This study proposes a method of detecting, locating, and quantifying structural damage by directly using structural vibration measurements in the time domain. In this method, the coupling effect of the damage at different ...
Temperature, Combustion, and Emissions on a Diesel Engine Using N-Butanol/Diesel Compound Combustion Mode
Publisher: American Society of Civil Engineers
Abstract: By adding an injection system of n-butanol on the intake manifold, the four-cylinder direct injection (DI) diesel engine had been modified to operate in n-butanol/diesel compound combustion mode (BDCC). Effects of temperature, ...
Detection of Changes in Global Structural Stiffness Coefficients Using Acceleration Feedback
Publisher: American Society of Civil Engineers
Abstract: This technical note presents an extension of a previous study where two methods for detecting structural damage have been developed by using displacement and velocity measurements. In this study, acceleration feedback is ...
Vision Guided Dynamic Synchronous Path Tracking Control of Dual Manipulator Cooperative System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compared with a single manipulator manufacturing cell, a dual manipulator cooperative system has more advantages in reconfigurability and flexibility. However, there are calibration errors and multi-source disturbances in ...
Predicting the Intensity of Tropical Cyclones over the Western North Pacific Using a Dual-Branch Spatiotemporal Attention Convolutional Network
Publisher: American Meteorological Society
Interannual Variability of the Basinwide Translation Speed of Tropical Cyclones in the Western North Pacific
Publisher: American Meteorological Society
Abstract: Understanding variations in tropical cyclone (TC) translation speed (TCS) is of great importance for islands and coastal regions since it is an important factor in determining TC-induced local damages. Investigating the ...
