摘要：
We consider nonlinear systems in feedforward form and redesign-nested saturation control laws to guarantee global asymptotic stability in the presence of unmodeled dynamics appearing at the system input. Unlike most previous results, this redesign is applicable to a large class of unmodeled dynamics, including actuators that change the relative degree of the system. (C) 2000 Elsevier Science Ltd.
