【Abstract】 As the system’s controlling inputs and operating region are constrained in real power systems, the decoupled and linearized system derived by ANN inversion method is not an ideal one. So the anticipant system’s responding characteristic should be appropriately determined when designing a closed loop controller for the decoupled system. By analyzing the input output responses of the controlled power system and the dominant physical characteristic of each decoupled subsystem, this paper presents a systematic method of how to determine reasonable closed loop anticipant responding characteristics and how to design the closed loop controller for each subsystem. As an example, the detailed design procedure of closed loop controller and simulation results for the excitation and valve control based on ANN inversion decoupling and linearizing method are given.更多还原
