摘要
The robust stability for neutral systems with mixed delays and uncertainties was investigated. The uncertainties under consideration were nonlinear perturbations and norm-bounded uncertainties, respectively. A novel Lyapunov-Krasovskii functional was constructed and its positive definiteness was proved by using integral inequality, which relaxed the constraint on some functional parameters. The neutral-delay-dependent and discrete-delay-dependent stability criteria for two different forms of uncertainty were derived by using Lyapunov method in terms of linear matrix inequalities. Then the conservatism caused by neutral-delay-independence was relaxed. The numerical examples were given to illustrate the effectiveness of the method and the improvement over some existing methods.
