摘要：
Based on multi-objective optimization, the design method of a magnetic levitation controller for electromagnetic suspension is proposed in this paper. First, we modify the output feedback system with a reduced order observer as the static output feedback system in order to simplify the optimization problem. By solving the modified optimization problem, the state feedback control gain is obtained such that the controlled system guarantees the mixed H-2/H-infinity norm bound of the transfer function between exogenous inputs such as noises and disturbances and controlled outputs.
