摘要: This paper considers the problem of almost disturbance decoupling (ADD) via sampled-data output feedback control for a class of uncertain nonlinear systems subject to time-delays. Based on output feedback domination approach, a sampled-data output feedback controller is designed to globally stabilize the system under a lower-triangular linear growth condition. Gronwall-Bellman-like inequality and inductive method are introduced to estimate the state growth in the presence of time-delays, uncertain nonlinearities and unknown disturbances. The proposed controller can attenuate the influence of disturbances on the output to an arbitrary degree in the L-2 gain sense. Finally, simulation results show the effectiveness of the control method.
