摘　　要：为研究线性时滞广义系统的渐近稳定性问题,利用时滞分割法均匀分割时滞区间,构造包含多重积分的Lyapunov-Krasovskii泛函以充分利用各子区间的时滞信息,并利用改进的Wirtinger型积分不等式估计泛函导函数的更紧上界,进而建立判定系统渐近稳定的时滞相关充分条件.最后,通过对比3个数值算例的仿真结果,证明了方法的有效性和先进性.Aimed at the asymptotic stability of linear time-delay singular system,the time-delay interval was evenly divided by using the time-delay division method,and a Lyapunov-Krasovskii functional(LKF)with multiple integral terms was constructed to effectively utilize the time-delay information of each sub-interval.Next,some improved Wirtinger-type integral inequalities were employed to estimate the LKF derivative and obtain a tighter estimation.Then,delay-dependent sufficient conditions were established to ensure the asymptotic stability of the addressed system.Finally,by using three numerical examples,comparisons and simulations were presented to illustrate the efficiency and superiority of the proposed method.
