This paper studies the leader-following consensus problem for heterogeneous multi-agent systems composed of linear second-order integrator agents and nonlinear Euler-Lagrange agents in two aspects. The consensus problem of heterogeneous multi-agent systems is discussed with unknown velocities, time-varying disturbances and packet dropout by introducing extended state observer. Sufficient conditions are established to ensure that all following agents could reach consensus with a virtual leader, which provide the allowable upper bound of packet drop rate. Numerical simulations are presented to illustrate the theoretical results. Keywords Extended state observer (ESO) heterogeneous multi-agent systems leader-following consensus packet dropout
