Formation reconfiguration control of quadrotor UAVs based on adaptive communication topology

This paper focuses on the cooperative control problem in formation reconfiguration of multiple flight vehicles, and the method of integral sliding mode control (ISMC) based on switching communication topology is investigated. The multiple flight vehicle system is modeled involving the connecting of communication topology and the character of formation reconfiguration of quadrotor UAV. The switching condition of the communication topology is raised considering the possible communication reliability problem in the process of formation reconfiguration. The cooperative controller is designed by ISMC method under the condition of switching topology communication, and its stability is proved adopting switching system theory. The simulation results show that the stability of UAV formation system can be ensured with ISMC method and switching communication topology in the process of formation reconfiguration, and illustrate the effectiveness of the proposed method.
