A robust tracking control problem that existed in the UAV formation and effectively proposes coordination tracking control strategy to resolve the underlying problem under the directed network time delay in UAV formation is examined in this study. First, a directed network topology-based formation model for the UAV with disturbance and network time delay is developed. The UAV formation coordination control method is subsequently created to address the time delay issue. Simultaneously, the H, performance index has been employed to enhance the formation robustness while accomplishing the purpose of coordination tracking control. Finally, the efficiency of the control strategy has been proven by simulation in this paper.
