This article investigates the event-triggered cooperative adaptive optimal output regulation problem for unknown multiagent systems (MASs) under switching network. To address communication disruptions between subsystems and the leader, a distributed observer is provided to estimate the reference signals. Without using system dynamics, an event-triggered mechanism is established to reduce computation and communication costs. Then, event-triggered adaptive optimal controllers are developed by using the available input/state data. By exploiting the Lyapunov stability theory and the method of input-to-state stability (ISS), rigorous stability analysis is conducted, and conditions for MASs to achieve the leader-to-formation stability (LFS) are provided. Additionally, the sensitivity of the suboptimality index to system parameters is analyzed. Finally, an application to cooperative adaptive cruise control (CACC) is presented to validate the proposed approach.
