A class of adaptive attenuation problem for a class of nonlinear parametrized time-delay systems with unknown virtual control coefficients is studied. An adaptive H_∞ controller is constructed by using parametric separation technique and backstepping design method. The closed-loop system is input from interference to the system under L_2 gain The influence of the output is arbitrarily small, and the system is stable when there is no external disturbance.
