Chaos is an inherent phenomenon of nonlinear system. Power system is a typical nonlinear system and it is likely to emerge chaotic oscillation or instability under periodic load perturbation. In order to suppress chaotic oscillations, this paper aim to delayed feedback inhibition of chaotic oscillation power system slow convergence and simulation ineffective, proposing a new method in the delayed feedback control based on the superposition of the Backstepping controller, it is proved by Lyapunov stability theory that the controlled system which can obtain closed loop asymptotically stable. Finally, a numerical simulation case study is given to prove the validity of the proposed method.
