Command-filtered adaptive backstepping control for marine power system

In order to retrain chaotic oscillation of marine power system which is excited by periodic electromagnetism perturbation, command-filtered adaptive backstepping method is used to design the chaotic controller based on the two parallel nonlinear mathematical model. Lyapunov stability theory is applied to prove that the system can remain close-loop asymptotically stable with this controller. Simulation results indicate that the designed controller can suppress chaotic oscillation with fast convergence speed, that make the system return to the equilibrium point quickly, meanwhile the parameter which induces chaotic oscillation can also be discriminated.
