| Abstract: | In order to coordinately enhance the voltage regulation accuracy and transient stability of power systems,a nonlinear switched excitation controll method is put forward based on the hierarchical control principle.The feedback linearization of the system is realized via the inverse system method.By using the Lyapunov function method,a switched excitation controller is designed for the partial linearized power system with zero dynamics.Simulation results on the professional testing software for power systems ... |
