Modelling, Characterisation and Force Tracking Control of a Magnetorheological Damper Under Harmonic Excitation

This is my first publication that is published in Inderscience Publisher

Abstract: The objective of this paper is to study the performance of a sixth order polynomial
approach to model hysteresis behaviour of a magnetorheological (MR) damper under harmonic
excitations. The polynomial model is developed based on curve fitting from the experimental
results and consists of a pair subsystem namely positive and negative acceleration which
correspond to the upper and lower curves. The performance of the proposed polynomial model is
compared with a well known non-parametric technique namely inverse model. The energy
dissipated and equivalent damping coefficient of the MR damper in terms of input current and
displacement amplitude are investigated. From the simulation results, the sixth order polynomial
model shows better performance in describing non-linear hysteresis behaviour of the MR damper
compared with inverse model. The force tracking control in both simulation and experimental
studies demonstrate that a close-loop PI control has the ability to track the desired damping force
well.
