Model Free Backstepping Control for Marine Power Systems

In order to retrain chaotic oscillation of marine power systems which are excited by periodic electromagnetism perturbation, in this paper, a novel model free backstepping control methods are designed. First, the dynamic model of marine power system is established based on the two parallel nonlinear model. Then, extended state observer (ESO) is de- signed to estimate the velocity signal and unknown function. Next, the model free backstepping controller is proposed based on the ESO. Finally, simulation results demonstrate the proposed model free control algorithm can quickly retrain chaotic oscillation. And it shows the proposed control method is effectiveness and potential.
