A New Control Algorithm for Active Suspension Systems Featuring Hysteresis

چکیده
In this paper the vibration suppression problem relative to the vertical motion of road vehicles is investigated. In particular, the goal of the research is to design control laws for active suspension systems of road vehicles in order to reduce unwanted vibrations induced by a rough road profile. The road vehicle has been represented with a quarter-car model whereas the suspension system has been schematized using the Bouc-Wen hysteresis model. In addition, a control actuator has been collocated between the sprung mass and the unsprung mass. Since the problem under study is nonlinear, the time history of the control action has been obtained numerically using the iterative adjoint-based control optimization method. Simulations show that the designed control action significantly mitigates the vibrations induced by the road profile.
