摘要：

This study is concerned with the adaptive stabilisation problem for a class of large-scale output-constrained non-linear time-delay systems in strict-feedback form. The investigative system satisfies a more general growth condition and the precise knowledge of the time delay is not required to be known a priori. Firstly, an observer is designed by the dynamic gain control design technique. Then, based on a novel Lyapunov-Krasovskii functional, the output constraints are satisfied and the stability of the closed-loop control system is achieved. Finally, a numerical example is given to demonstrate the effectiveness of the proposed design procedure.
