Iterative model-based mixed H2/H∞ control design

This paper proposes an Iterative scheme for mixed H-2/H-infinity control design using an identified model. The purpose of the mixed H-2/H-infinity is to combine the traditional H-2 quadratic performance criterion for disturbance rejection with the H-infinity performance criterion for the maximum robustness against destabilizing uncertainties. In the iterative scheme, once the model is identified for the known controller, once the controller is designed for the identified model. This paper demonstrates this scheme for the active suspension design in which the traditional performance criterion should be extended with H-infinity criterion due to significant uncertainties.
