| Summary: | Semi-active control devices have received significant attention in recent years because they offer the
adaptability of active control devices without requiring the associated large power sources.
Magneto-rheological (MR) dampers are semi-active control devices that use MR fluids to produce
controllable dampers. They potentially offer highly reliable operation and can be viewed as fail-safe in
that they become passive dampers should the control hardware malfunction. To develop control algorithms that take maximum advantage of the unique features of the MR damper, models must be
developed that can adequately characterize the damper’s intrinsic nonlinear behavior. Following a
review of several idealized mechanical models for controllable fluid dampers, a model is proposed that
can effectively portray the behavior of a typical magneto-rheological damper. Comparison with
experimental results for a prototype damper indicates that the model is accurate over a wide range of
operating conditions and is adequate for control design and analysis. |
