Abstract EN
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.
The source of hysteresis in MR dampers is twofold.
First, it is due to the compressibility and inertia of the fluid.
Second, magnetic hysteresis is the inherent property of ferromagnetic materials that form the control circuit of the valve including MR fluid.
While the former was studied extensively over the past years using various phenomenological models, the latter has attracted less attention.
In this paper, we analyze the magnetic hysteretic behaviour of three different MR dampers by investigating their current-flux relationships.
Two dampers operate in flow mode, whereas the third one is a shear-mode device (brake).
The approach is demonstrated using a sensorless magnetic flux estimation technique.
We reveal the response of the dampers when subjected to sinusoidal inputs across a wide range of operating conditions and excitation inputs.
Our observations of the flux data showed that the hysteresis is influenced by both amplitude and the frequency of the excitation input.
The procedure allows to analyze the magnetic hysteresis independently of other sources of hysteresis in MR dampers; on this basis, more effective damper models and control algorithms can be developed in the future.
