摘　　要：研究了一类不确定中立型系统的时滞依赖稳定性问题.利用基于LMI正定解的存在性,给出了一个新时滞依赖型稳定性判据,相比于已有文献本文具有低的保守性.最后通过数值算例验证了本文得到的结论的正确性和有效性.The delay-dependent robust stability problem is investigated for a class of neutral systems with uncertainties. A new delay-dependent stability criterion is obtained in the form of linear matrix inequalities via novel Lyapunov Krasovskii functional. The result obtained is less conservative than those obtained in former literature. Finally, numerical examples are given to show the correctness and effectiveness of the main results.
