Suspension Control Applications of Magnetorheological Damper Magic Formula Model

The parameters of the magnetorheological damper magic formula model were identified based on the experimental data of a certain magnetorheological damper. The errors of the model were within 8%. Under the conditions of simplifying the magic formula of magnetorheological dampers, the reverse model of the magnetorheological damper magic formula was obtained by direct inverse thrust. In the simulations, when the magnetorheological damper magic formula positive and inverse models realized the expected damping forces of the ADD control strategy, the average errors are 3.67%. In the bench test, the applications of the inverse model of the magnetorheological damper magic formula reduces the body acceleration of 6.27% and realize the control effectiveness of the new control strategy. Finally, the magnetorheological damper magic formula model was successfully applied to the semi-active control suspension system simulation and bench test. The research on magnetorheological semi-active suspension control system has strong practical significance.
