摘要
The previously proposed delay-dependent robust stability criteria for a class of uncertain mixed neutral and Lure dynamical systems with interval time-varying delays are refined by eliminating nonlinearity and/or reducing the number of free-weighting matrices. Several robust stability criteria proposed in this paper are simpler and effective. Numerical examples show that the new method is less conservative than some previous approaches.
