In this work, we study the delay-dependent exponential passivity and stability analysis of neutral system with time-varying delays and nonlinear perturbations. We derive new delay-dependent exponential passivity and stability conditions for the system in terms of linear matrix inequalities (LMIs) by constructing new class of augmented Lyapunov-Krasovskii functional, utilization of zero equation, descriptor model transformation, Leibniz-Newton formula and various inequalities. We also demonstrate the effectiveness and improvement of the results by giving some numerical examples.
