This paper presents a new model of generator excitation controller that is derived from autodisturbance-rejection controller (ADRC). The new controller inherits the advantage of traditional PID regulator such as simple structure, strong robustness and adaptability to different plants, but not the disadvantages derived from the linearization of operating point. The parameters are tuned on-line based on neural PID principle. The new power system stabilizer is applied to a typical single-machine infinite bus system that is subject to transient disturbances. Numerical simulation shows that the auto-disturbance-rejection-excitation controller is effective.
