摘 要：This paper investigates the group consensus problem of continuous-time second-order multi-agent systems（MASs）with asynchronous sampling, where each agent has its own clocks that are not affected by the others’. The asynchronous sampleddata based protocol is designed by using the neighbors’ state information with uncertain time-varying sampling intervals. In continuous-time second-order MASs, the asynchronous group consensus problem can be equivalently transformed into a stability problem of synchronous discrete-time second-order MASs by using appropriate model transformations. With the help of the nonnegative matrix theory and graph theory, the stability is analyzed and a pretty graphic sufficient condition is established.Besides, a simulation example is given to demonstrate the proposed result.
