【Abstract】 The robust control problem of power systemis investigated in this paper. A novel controller for the generator excitation system is set up based on a combination ofH∞ control theory and feedback linearization approach. Theproperties of the controller are its complete decentralizationand robustness. The design is well suited to a multimachinesystem where it is not based on a infinite-bus aproximation.Simulation performed on a 13-machine system shows thatthe proposed controller can not only improve the dynamicperformance of the power system, but also can enhance thesystem stability, especially the stability against Iarge disturbance.更多还原
