Fault-tolerant Control Law for Unmanned Aerial Vehicle Array Based on Sliding Mode Control

Unmanned aerial vehicle array(UAV array) has become the focus of many researchers as a feasible solution to solve the problem of short endurance and weak load capacity. After investigating the research status and key problems of UAV array at home and abroad, this paper establishes the array dynamics model composed of a new configuration of the quadrotor flying array with the main and auxiliary rotor structure under the triangular prism frame. Based on this model, a sliding mode control method is designed to solve the fault-tolerant control problem of UAV array. In order to further verify the control performance of the proposed control algorithm, typical topology structures were selected as experimental representatives to complete the control simulation design and experiment of the system. The results show that this algorithm can achieve good control effect.
