Abstract:

The stabilization problem via the linear output feedback controller is addressed for a class of nonlinear systems subject to time-delay. The uncertainty of the system satisfies the lower-triangular growth condition and it is affected by time-delay. A linear output feedback controller with a tunable scaling gain is constructed. By selecting an appropriate Lyapunov-Krasovskii functional, the scaling gain can be adjusted to render the closed-loop system globally asymptotically stable. The results can also be extended to the non-triangular nonlinear time-delay systems. The proposed control law together with the observer is linear and memoryless in nature, and, therefore, it is easy to implement in practice. Two computer simulations are conducted to illustrate the effectiveness of the proposed theoretical results.
