This paper presents an adaptive-approximationbased
distributed leader-following fault-tolerant tracking control
scheme for a class of high-order nonlinear uncertain multiagent
systems. The time-varying leader only communicates
to a small portion of follower agents through directed links,
and each follower agent exchanges measurement information
only with its neighbors through a bidirectional but asymmetric
topology. Under certain assumptions, the closed-loop stability
and asymptotic leader-follower tracking properties are rigorously
established even in the presence of multiple
