Sampled-Data Consensus Protocols for a Class of Second-Order Switched Nonlinear Multiagent Systems
IEEE Transactions on Cybernetics, 2022In this study, the sampled-data consensus problem is investigated for a class of heterogeneous multiagent systems (MASs) in which each agent is described by a second-order switched nonlinear system.
