Distributed event‐based consensus disturbance rejection with parameter uncertainties

Summary This article investigates the distributed consensus disturbance rejection problem of general linear multiagent networks via the observer‐based event‐triggered control approach. By adopting the Lyapunov method, it can be proved that the distributed consensus is achieved in the presentence of matched disturbances under the proposed observer‐based event‐triggered controllers when the parameter uncertainties are not considered. Then the results are extended to the cases with parameter uncertainties. Compared to the related works, the main contribution is that the eigenvalue information of the Laplacian matrix is not required in both the controller design and the updating rule design. Moreover, continuous communications between agents can be avoided in the proposed event‐based control scheme. Simulation examples are provided to illustrative the effectiveness of theoretical results.
