Output feedback control of a class of time-delay nonlinear systems

This paper is concerned with the problem of global stabilization by output feedback for a class of time-delay nonlinear systems that are dominated by a triangular system satisfying linear growth condition. By constructing the appropriate Lyapunov-Krasovskii functionals (LKF), the linear and memoryless output feedback controller making the closed-loop system globally asymptotically stable (GAS) is explicitly constructed. An example is given to show that the proposed design procedures are very simple and efficient.
