摘要:

利用Lyapunov方法对变时滞的线性中立型微分系统的全局指数稳定性进行分析,并估计其指数收敛率,得到了两个实用的全局指数稳定性判据。这些稳定判据都表示为线性矩 阵不等式(LMI)形式,易于验证。数字仿真实例验证了所得结果的有效性。

Abstract:

By using the Lyapunov method for linear neutral differential systems with time-varying delays, the problems of determining the global exponential stab ility and estimating the exponential convergence rate are investigated in this paper. Two useful criteria of global exponential stability for the systems are derived. These stability criteria are formulated as linear matrix inequalities (LMIs) which can be easily validated. Numerical examples are give en to illustrate the effectiveness of the proposed method.
