【Abstract】 A new robust control scheme,which can be used for decentralized generator excitation systems and can effectively improve operation stability of warship electro-power system,is proposed.By using generator’s terminal voltage magnitude and phase angle to present the interaction among generators,decentralized generator excitation control in a multi-generator power system is achieved.The control is realized by utilizing a interference rejection control based on a robust control design approach.Simulation results show that the proposed robust excitation control strategy can overall improve warship electro-power system’s stability.更多还原
