Robust design of active suspension system
by P. Michelberger, L. Palkovics, J. Bokor
International Journal of Vehicle Design (IJVD), Vol. 14, No. 2/3, 1993

Abstract: In this paper, the authors deal with some new control design methods of the control system used in active wheel suspension. Applicability of H_∞ control in case of the active suspension system is examined still using the familiar quarter-car model. The robust control problem is solved in case of direct state-feedback H_∞ and in the presence of structured (parametric) uncertainties solving the RLQR design task. The authors solve the joint H_∞/RLQR problem proving the trade-off between the external disturbance rejection (road irregularities) and the internal disturbance attenuation arising from the parametric uncertainties.
