Novel delay-dependent robust stability criteria for neutral systems with mixed time-varying delays and nonlinear perturbations

摘要

This paper investigated the problem of delay-dependent robust stability criteria for neutral systems with mixed time-varying delays and nonlinear perturbations. A piecewise delay method is used in this paper, the variation interval of the time delay is divided into two subintervals by introducing its central point. Then, by employing the new Lyapunov–Krasovskii functional and linear matrix inequality technique, some new sufficient conditions are obtained. At last, numerical examples are provided to demonstrate the effectiveness of the obtained results.
