Abstract
This paper investigates the problem of leader-follower formation control under malicious communication attacks. A flight vehicle group consisting of one leader and several followers is considered to achieve a desired formation and maintain it when encountering the false data injection attacks (FDIAs). Two kinds of fault-tolerant formation control methods are presented with practical finite-time convergence. The former is based on a distributed position observer which estimates the information of the leader, and the formation is established by enforcing the followers to track their expected positions related to the estimated leader's information. While the latter is an observer-free adaptive formation control strategy. For the communication attack resistance, the confidence factors and trust factors are constructed and equipped in both methods. The simulations are conducted to validate the effectiveness of the proposed fault-tolerant formation control strategies.
