Adaptive output feedback control for a class of large‐scale output‐constrained non‐linear time‐delay systems

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.
