Abstract: This work optimizes a dynamic vibration absorber (DVA) model equipped with an additional amplifying mechanism using the H∞ optimization criterion, which aims to minimize the maximum frequency response amplitude of the ...

Abstract: AbstractIn this paper, a distributed economic nonlinear model predictive control (DENMPC) is proposed to decrease the energy consumption in attitude cooperative control of spacecraft formation flying. Unlike traditional ...

Abstract: The delayed resonator (DR) is an active vibration absorber, which yields ideal vibration suppression at its resonance frequency. In this study, we further complement the DR design in a distinctive mechanical path by ...

Abstract: The delayed resonator (DR) is known for its ideal vibration suppression and simple control logic, but its operable frequency range is also known limited due to stability issues and practical hardware constraints. To extend ...

Abstract: AbstractGeopolymer foam has good thermal insulation properties. Due to its numerous open pores, geopolymer foam requires a protective coating to prevent environmental moisture penetration. In this study, a novel inorganic ...
