Design of Close Formation Controller for UAVs Based on Fuzzy PID Rule
Bo Xu, Mingyu Jiao, Dalong Zhang · 2020
The compact formation of UAVs is a formation in which the lateral distance between UAVs is twice the wingspan. Because it can effectively improve the aerodynamic performance of UAVs in formation, thereby reducing resistance, saving fuel, extending the duration, and also can confuse the enemy air defense system with the information of a super-large transport aircraft on the radar screen to achieve unexpected combat purposes, it has attracted much attention. In this paper, the aerodynamic coupling effect of UAV in close formation is studied, and the state space equation in three-dimensional space is established to describe the state of two UAVs. The fuzzy PID formation controller is designed and the effectiveness of the controller is verified by simulation.
