| Abstract: | Robust adaptive control problem is investigated for a class of nonlinear time-delay systems.By using backstepping method,state feedback controller and adaptive control law are constructed skillfully.Lyapunov functionals are chosen properly to deal with the time-delay terms of the systems.Based on Lyapunov stability theory,the constructed control laws can render that the closed-loop system is asymptotically stable.Finally,a numerical example and simulation results are given to illustrate the effectiveness of the proposed method. |
