摘要: 研究了带有区间时滞的不确定系统的稳定性问题。通过采用时滞分割法,把时滞区间分割成任意两小段,并构造恰当的Lyapunov函数,利用积分不等式,得到了新的时滞相关的稳定性准则。通过数值例子验证了结果的有效性。

Abstract: The stability problem for uncertain linear systems with interval time-varying delay is studied. Based on the delay-
dividing approach, the delay interval is partitioned into two subintervals. By constructing an appropriate Lyapunov function and using integral inequalities, some delay-dependent stability criteria are obtained. Numerical examples are given to illustrate the effectiveness of the results.
