A Novel Simplified and High-Precision Inverse Dynamics Model for Magneto-Rheological Damper

Abstract:

Due to the virtue in energy consumption, response time and work reliability, the magneto-rheological (MR) damper is a new promising devices for vibration control, in which the controller input expected control force and piston velocity to justify MR damper input voltage, so that desired damper force is achieved. It follows that the functional relationship between input voltage, expected control force and piston velocity is important for MR damper application. In this paper, a novel simplified and high-precision inverse dynamics model is derived based on MR damper Bouc-Wen phenomenological model, by which the input voltage of MR damper is calculated by means of expected control force and piston velocity. To verify the validity of this proposed inverse dynamics model, two numerical simulations of MR damper force following tests are introduced in the latter of this paper.
