...Jian Ding; Xiaotong Jiang; Yuchun Zou; Zhen Tang; Ziyang Zhen Purpose A multivariable model reference adaptive control method is proposed to solve a distributed leader–follower formation control problem of unmanned aerial vehicles (UAVs) with uncertain parameters and unknown external disturbances...

... to prevent infinite triggering instances within a finite time. Finally, simulations are conducted with external disturbances and actuator failure conditions to demonstrate formation tracking controller performance. Findings It achieves improved performance in the presence of external disturbances...
