Delay dependent stability for uncertain time-delay systems

讨论具有非线性摄动的时滞不确定系统的时滞相关稳定性问题 .针对单时滞不确定系统 ,利用Lyapunov方法 ,通过构造一个参数相关的Lyapunov函数 ,并借助短阵不等式和矩阵特征值及矩阵范数的性质 ,给出了单时滞不确定系统时滞相关渐近稳定的判别条件 ,并将所得结果推广到多时滞不确定系统 ,得到了多时滞不确定系统时滞相关渐近稳定的判别条件 .基于所得判别条件建立了相应的“分层递推”算法 ,使得条件的判断容易实现 .一个二维系统的算例验证了该算法的可行性 .

The conditions for delay dependent asymptotic stability are given for the single time delay system by applying Lyapunov approach and structuring a parameter dependent Lyapunov function and using the property of matrix characteristic value and matrix norm, and the results obtained for the single time delay system are extended to the uncertain multiple time delay system. The relevant algorithms of 'stratified recursive' are presented such that the conditions obtained are easy to realize and the feasiblity of the algorithms obtained is illustrated by an example.
