【Abstract】 Robust H∞ control problem for a class of time-delay nonlinear systems is discussed.A recursive Lyapunov-based design approach is developed to construct a new control law and H∞ controller.By choosing ideal Lyapunov functionals skillfully,the time-delay term of nonlinear systems is dealed with.Furthermore Backstepping method is extended.Finally,illustrative example and simulation results verify the correctness of the conclusion.更多还原
