SUMMARY This paper is concerned with the leader–follower flocking problem of networked nonholonomic multi‐agent systems with non‐identical unknown nonlinear dynamics. The leader motion to be synchronized is also nonlinear and unknown. By employing the graph theory and a pinning control technique, a distributed neural adaptive control design is developed for the agents to achieve motion synchronization with the leader. The design is for a directed communication graph with a fixed topology. A collective potential function is used to maintain cohesion between the agents. On the basis of Lyapunov analysis, the developed neural flocking algorithm guarantees that all the agents’ headings and speeds are synchronized with the leader and collisions between the agents can be avoided. An illustrative example is given to show the effectiveness of the proposed control strategy. Copyright © 2013 John Wiley & Sons, Ltd.
