摘要
研究了中立型时滞系统时滞相关稳定性,其中包括定常时滞中立型系统的相关稳定性和不确定系数时滞中立型系统的时滞相关稳定性.通过对系统方程构造适当的Lyapunov函数和添加适当的零项,采用线性矩阵不等式(LM I)方法给出此类系统稳定性的判别依据.通过与已有结论比较,显示本文给出判别准则的正确性且具有较小的保守性.
The delay-dependent stability criteria for a class of constant time-delay neutral systems are studied, inclu, ding the stability criteria for invariable coefficient time-delay neutral systems, and the stability criteria for constant time-varying neutral systems with time-varying structured uncertainties. By constructing appropriate Lyapunov func, tion, adding some appropriate zero terms of the systerm equation, some sufficient conditrons for discrete delay-dependent and neutral delay-independent stability are derived in terms of the solutions of linear matrix inequality. Compared with the previous results by some numerical examples, the results obtained in the experiment are effective and less conservative.
