In　this　paper,　the　leader-following　consensus　problem　of　a　class　of　first-order　nonlinear　multiagent　systems　is　studied.　Since　the　agent　is　usually　driven　by　electromechanical　devices　in　the　working　process　and　the　system　is　in　a　complex　communication　network,　this　paper　considers　the　unknown　external　disturbance　of　the　agent’s　actuator　state　and　the　topology　diagram　with　unknown　weights.　By　introducing　adaptive　parameters,　a　fully　distributed　leader-following　consensus　protocol　is　developed.　It　is　worth　noting　that　the　design　of　the　controller　does　not　need　to　rely　on　any　global　information,　which　greatly　broadens　the　practicality　of　the　scheme.　Finally,　a　simulation　example　is　given　to　verify　the　effectiveness　of　the　proposed　strategy.　©　2024　Copyright　held　by　the　owner/author(s).
