摘要：AbstractIn this paper, a class of lower-triangular systems with time delays both in the nonlinearities and control input are globally stabilized by sampled-data output feedback control. The output feedback domination approach is developed to globally stabilize the time-delay nonlinear system. Based on a linear discrete observer, a sampled-data output feedback controller is explicitly designed, in which a scaling gain is introduced by a new coordinates change of the system to dominate the nonlinearities. Since the separation principle is not satisfied, a novel Lyapunov-Krasovskii functional is constructed to analyze the stability of the closed-loop system. Some sufficient conditions about the gains and time-delays are derived. Simulation results are provided to illustrate the correctness and effectiveness of the proposed method.
