The H_∞ containment control problems for first-order multi-agent systems with multiple time-varying delays under directed network topology are investigated.Firstly,by introducing a convergence vector function,the H_∞containment control problems of multi-agent systems are transformed into the H_∞ control problems of normal time-delay systems.Then,by using the Lyapunov stability theory,a suitable Lyapunov-Krasovskii functional is designed.Some sufficient conditions for H_∞ containment control are established ...
