Motivated by the design of disturbance observers with active elimination of the adverse effects caused by system uncertainties and disturbances, the problem of semi‐global exquisite disturbance attenuation control for a class of perturbed nonlinear systems is investigated in this paper. A feedback domination technique is utilized to integrate with the disturbance observer design and then a general composite active anti‐disturbance control law is proposed. With a recursive design procedure, the mismatched lumped disturbances are compensated in a novel step‐by‐step way while the non‐vanishing nonlinearities are treated via a feedback domination approach, rather than utilizing the straightforward feedback linearization method. The closed‐loop control performance and disturbance rejection ability now can be improved. A rigorous stability analysis assures the effectiveness of the proposed strategy. Numerical simulation results affirm the improved control and disturbance rejection performances with respect to several related existing results.
