Biologically-Inspired Impedance Control With Hysteretic Damping

IEEE Control Systems Letters, 2021
Recent experiments have shown that human joints can maintain a constant damping ratio across a wide range of external loads. This behavior can be explained by the use of a “complex stiffness” frequency-domain model approximating the impedance of the human joint.

Hysteretic damping revisited

Advances in Engineering Software, 1997
Abstract An integral-differential equation (IDE) in the time domain has been proposed for the free vibration of a single-degree-of-freedom (SDOF) system with hysteretic damping which is different from the conventional complex stiffness model as employed in the frequency domain (Chen & You, Proposal NSC 85-2211-E-019-004, National Taiwan Ocean ...

On a Kind of Hysteretic Damping

Journal of the Engineering Mechanics Division, 1964
Slightly nonlinear materials and structures with purely hysteretic damping, subjected to harmonic disturbances, are examined. It is shown that a load-deformation or stress-strain relation, on first loading, supplemented by a rule to obtain the curves on unloading and reloading, leads to a behavior similar to that of a linear viscoelastic material, but ...

Hysteretic and viscous material damping

International Journal for Numerical and Analytical Methods in Geomechanics, 1980
AbstractHysteretic and viscous material damping are compared in the context of soils. Popular assumptions about damping are shown to lead to different results for the rocking mode of surface foundations at low frequency.

Equivalent Viscous Damping of Bilinear Hysteretic Oscillators

Journal of Structural Engineering, 2015
AbstractAn improved formula to determine the equivalent viscous damping ratio of a single-degree-of-freedom (SDOF) bilinear oscillator is proposed in this paper, which simultaneously considers the influence of the initial period, ductility ratio, and strain hardening ratio.

Hysteretic damping and causality

Acoustical Physics, 2013
It is proven that linear oscillatory systems with hysteretic damping in the form of complex stiffness and/or complex elastic moduli satisfy the causality principle: the response of such a system to an arbitrary external force cannot appear earlier than the onset of the force. The proof, based on a rigorous solution to the problem of forced oscillations,

Hysteretic damping in rotordynamics: An equivalent formulation

Journal of Sound and Vibration, 2010
The hysteretic damping model cannot be applied to time domain dynamic simulations: this is a well-known feature that has been discussed in the literature since the time when analog computers were widespread. The constant equivalent damping often introduced to overcome this problem is also discussed, and its limitations are stated, in particular those ...

Practical causal hysteretic damping

Earthquake Engineering & Structural Dynamics, 2006
AbstractA number of experiments indicate that the internal damping corresponding to the energy dissipation of many materials is essentially frequency independent. Accordingly, an analysis model that can express such characteristics (called a hysteretic damping model) in the time domain is needed.
