This chapter investigates the problem of finite-time leaderless consensus of networked multi-agent systems with first-order uncertain dynamics under local communication topology condition. Finite-time convergence behavior is of special importance in cooperative control of MAS, but the vast majority research on finite-time control of MAS has been focused on linear systems or nonlinear systems with nonlinearities that can be linearly parameterized, that is, the nonlinearities in that systems are assumed to exhibit the linear parametric property. The control results on finite-time distributed control of nonlinear MAS with unknown non-parametric and non-vanishing uncertainties are scarce. Extending the existing finite-time control methods for linear systems or nonlinear systems with linearly parameterized nonlinearities to MAS subject to non-parametric and non-vanishing uncertainties encounters significant technical challenge. The main hindrance stems from the fact that, in the presence of the non-parametric uncertainties, the commonly used adaptive control law cannot be used to derive the finite-time convergence because it can not ensure an important relation that is crucial to derive the finite-time convergence result.
