In order to improve the control effect of the generator excitation controller, this paper proposes an excitation control based on objective holographic feedbacks and extended state observer. First, nonlinear factors of the nonlinear equation is switched to the state equation which contains the control input factors by objective holographic feedbacks. Then, constructing a second extended state observer tracks and compensates uncertain disturbance, simultaneously reduces system parameters of control law. Finally, MATLAB is used for simulation, the results show that nonlinear excitation controller that this paper designs can not only improve static and transient stability of system, but also improve the precision and stability of the terminal voltage control better. |
