针对带分布时滞的奇异中立型系统进行稳定性研究。基于交互式凸组合方法和Finsler引理,通过适当分割时滞区间,构造恰当的李雅普诺夫函数,从而处理一组权数为凸参数的逆的线性正函数组合(交互式凸组合),减少带分布时滞的奇异中立型系统稳定性判据的决策变量,给出系统是正则的,无脉冲的,渐近稳定的充分条件,该条件以线性矩阵不等式形式表示。数值例子验证了该方法的有效性。
針對帶分佈時滯的奇異中立型繫統進行穩定性研究。基于交互式凸組閤方法和Finsler引理,通過適噹分割時滯區間,構造恰噹的李雅普諾伕函數,從而處理一組權數為凸參數的逆的線性正函數組閤(交互式凸組閤),減少帶分佈時滯的奇異中立型繫統穩定性判據的決策變量,給齣繫統是正則的,無脈遲的,漸近穩定的充分條件,該條件以線性矩陣不等式形式錶示。數值例子驗證瞭該方法的有效性。

The robust stability problem for singular neutral system with distributed time‐varying delays is researched .Based on reciprocally convex combination approach ,which is a way of handling a linear combination of positive functions weighted by the inverse of convex parametersfreciprocally con‐vex combinationl and reducing the stability criterion’s number of decision variables ,the sufficient conditions are given in terms of linear matrix inequalities by partitioning delay intervals properly and constructing an appropriate Lyapunov functional ,w hich ensued the system is regular ,impulse free and asymptotic stability .A numerical example is presented to show the effectiveness of the method .
