Abstract: Aiming at the problem that the control performance of the three-phase current-source inverter (CSI) is easily affected by load parameters and external disturbances easily, a robust H∞ control strategy is proposed in this paper. A mathematical model of the three-phase CSI is established. According to the model of CSI with uncertain parameters, the state feedback H∞ controller is designed and the feedback control laws are obtained. A robust H∞ controller based on CSI control system is designed. Finally, the effectiveness and feasibility of the scheme are verified by simulation.

Keywords: three-phase current-source inverter; robust H∞ control; state feedback; robustness.
