— This paper presents a distributed saturated formation control for a multiple quadrotors (UAVs) system with leader-follower structure. Each UAV has local and limited neighbors. Stability analysis for the multi-UAV system with fixed and switching topology is given, using the theories of convex hull and perturbed matrix. Simulation results show that the quadrotors with the proposed strategy can achieve consensus in presence of changeable leaders with switching topology. The real-time experiment shows that the quadrotors can track the desired formation trajectory by using the proposed formation strategy.
