摘要:In this paper, some improved delay-dependent exponential stability criteria of the neutral delayed differential equation d d t [ x ( t ) + p x ( t − τ ( t ) ) ] + a x ( t ) − b tanh x ( t − σ ( t ) ) = 0 , are expressed in terms of linear matrix inequalities (LMIs). Compared with some existing ones, our results are derived without the use of the mode transformation method and the bounding technique. Three numerical examples are provided to show the effectiveness of the proposed method and less conservatism of the obtained results.
