Abstract : In this paper, the robust consensus of multi-agent dynamical systems with time-delays and exogenous disturbances is studied. A pinning control strategy is designed for a parts of agents of the multi-agent systems without disturbances, and this pinning control can bring multiple agents’ states to an expected consensus track. Under the effects of the disturbances, disturbance observers based control (DOBC) are developed for disturbances generated by an exogenous system to estimate the disturbances. Asymptotical consensus of the multi-agent systems with disturbances under the composite controller can be achieved for fixed and switching topologies. Finally, by applying an example of multi-agent systems with switching topologies and exogenous disturbances, the design of the parameters of DOBC are illuminated.
