Samenvatting
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.
