Structural behavior of steel slit damper in steel beam to column connection [PDF]
Journal of Structural and Construction Engineering, 2020 Most of the steel moment resisting frames, damage at the beam-to-column connections during seismic loads. Application of passive dampers in order to prevent damages to the main components of structure has been an interesting subject for many researchers ...

Controlled symmetries and passive walking [PDF]
IEEE Transactions on Automatic Control, 2002 In this note, we investigate the relationship between nonlinear control and passive walking in bipedal locomotion for the general case of an n degree-of-freedom biped in three dimensional space. We introduce the notion of controlled symmetry to capture the effect of the control input on the invariance of the system Lagrangian under group action.

Control analysis of virotherapy chaotic system
Journal of Biological Dynamics, 2022 In this work, we consider a chaotic system that plays a vital role in the treatment of cancer by injection of a virus externally. Due to the sensitivity of this disease, most of its treatments are highly risky.

Soil–Structure Interaction Consideration for Base Isolated Structures under Earthquake Excitation
Buildings, 2023 This study aims to analytically implement base isolation with soil–structure interaction (SSI) on a sample structure and to develop a very simple solution to add these combined effects into the mass, damping and stiffness matrices of the structure.

Latching and Declutching Control of the Solo Duck Wave-Energy Converter with Different Load Types
Energies, 2017 The solo duck wave-energy converter (WEC) captures power in a point absorber manner, hence it exhibits high power-capture efficiency within only a narrow bandwidth. Passive control is characterized by a unidirectional power flow, and thus its engineering

Krasovskii and Shifted Passivity-Based Control [PDF]
IEEE Transactions on Automatic Control, 2021 In this paper, our objective is to develop novel passivity based control techniques by introducing a new passivity concept named Krasovskii passivity. As a preliminary step, we investigate properties of Krasovskii passive systems and establish relations among four relevant passivity concepts including Krasovskii passivity.

Introduction of a new elliptical damper for seismic energy dissipation of civil structures [PDF]
مهندسی عمران شریف, 2022 In this paper, a new energy dissipative device named elliptical damper was introduced for passive control of structures. In the proposed damper, the energy dissipation capacity is provided by the shear deformation of the elliptical ring.
