This paper deals with the ℋH∞ DIA control system design attenuating initial-state uncertainties and its application to magnetic suspension systems. Here the ℋH∞, DIA control means a mixed Disturbance and an Initial-state uncertainty Attenuation(DIA) control for linear time-invariant systems in the infinite-horizon case. The ℋH∞ DIA control problem supplies ℋH∞ controls with good transients and assures ℋH∞ controls of robustness against initial-state uncertainties. We derived a necessary and sufficient condition of the generalized ℋH∞ DIA problem. In this paper, we apply this ℋH∞ DIA approach to magnetic suspension systems, and evaluate a mixed attenuation property of the proposed approach via experiments. We investigate a role of the weighting matrix N for the initial state uncertainty in the control system design.
