Modelling and inversion-based control of a magnetorheological vehicle suspension

In this paper, we present the development, modelling, and simulation of two semi-active control strategies applied on a magnetorheological (MR) suspension for automotive applications. A modified Sky-Hook strategy and a new control strategy based on the inversion of the Energetic Macroscopic Representation of the MR suspension are considered. A special scaled-down test bench was designed and manufactured to characterize the MR damper. Simulation results of both control strategies are shown and discussed especially from electrical energy consumption point of view as this is one the key criteria for the design of new vehicles.
