Output Feedback Stabilization by a New Dynamic Gain for a Class of Nonlinear Time-Delay Systems with Sensor Uncertainties

Abstract

This paper investigates the output feedback stabilization problem for a class of nonlinear time-delay systems with sensor uncertainties. A new dynamic gain observer and update law are introduced to solve the problem of multiplicative and additive uncertainty of output function. Finally, a reasonable choice of Lyapunov-Krasovskii functionals can prove that the state of the whole closed-loop system remains in a small neighborhood of zero. A simulation example is presented to demonstrate the effectiveness of the control strategy.
