The　secure　leader-following　consensus　problem　of　multiagent　systems　with　both　denial-of-service　(DoS)　attacks　and　input　saturation　constraints　is　investigated　in　this　note.　The　low-gain　technique　has　been　developed　for　designing　the　distributed　control　protocol　for　each　agent.　Explicit　analysis　of　the　duration　and　the　frequency　of　the　DoS　attacks　have　also　been　presented　in　order　to　guarantee　the　desired　secure　consensus.　The　stability　analysis　of　the　closed-loop　system　is　conducted　by　using　the　Lyapunov　function　method.　Some　simulations　are　presented　for　validating　the　effectiveness　of　the　presented　strategy.　©　2020　Technical　Committee　on　Control　Theory,　Chinese　Association　of　Automation.
