摘要：

This paper addresses the problem of non-fragile prescribed-time output feedback stabilization for a class of nonlinear systems with unknown measurement noise. Two Lyapunov matrix inequalities with uncertainties are introduced to mitigate disturbances in controller gains and noise in the measurement sensor. A novel high-gain function with a segmented adaptive law is proposed to ensure prescribed-time stability. Based on this, a non-fragile output feedback controller is designed to ensure that all signals in the closed-loop system remain bounded within a prescribed time and asymptotically converge at the origin. Finally, two simulation examples are provided to validate the effectiveness of the proposed control strategy.
