Assessment of the Magnetic Hysteretic Behaviour of MR Dampers through Sensorless Measurements
Shock and Vibration, 2018 Magnetorheological (MR) dampers are well-known devices based on smart fluids. The dampers exhibit nonlinear hysteretic behaviour which affects their performance in control systems. Hence, an effective control scheme must include a hysteresis compensator.

Tuned inerter dampers with linear hysteretic damping [PDF]
Earthquake Engineering & Structural Dynamics, 2020 SummaryThis paper explores the influence of linear hysteretic damping on the performance of passive tuned‐inerter devices. An inerter is a device that produces a force proportional to the relative acceleration across its two terminals; devices incorporating inerters have received widespread attention in the earthquake engineering community, because ...

Influence of a hysteretic damper on the flutter instability [PDF]
Journal of Fluids and Structures, 2017 The influence of a hysteretic damper on the airfoil flutter instability is investigated. In particular, its effect on the post-critical limit cycle oscillations (LCOs) is emphasized. For that purpose, an aeroelastic model including large amplitude motions and dynamic stall phenomenon, is considered for a rigid flat plate having two degrees of freedom ...
