Adaptive semiactive suspension system by linearly parameterized controller

The paper is concerned with adaptive semi-active control approaches which can deal with uncertainties in both models of MR damper and suspension mechanism. The proposed control schemes consist of two controllers: One is an adaptive damper controller for compensating the nonlinear hysteresis dynamics of the MR damper, which can be realized by identifying a forward model of MR damper or an inverse modeling directly. The other is a reference feedback controller which gives a desired damping force to be generated by the MR damper. Effectiveness of the proposed algorithms is examined in numerical simulations.
