In this paper, the hover control method of a thrust-vectoring aircraft is discussed, which is thefirst step to realize vertical takeoff and landing (VTOL) as a tail-sitter. To avoid the gimbal lock problem,vertical Euler angles are used and a new calculation method of them is presented. The attitude controllerswitches between horizon mode and vertical mode, with a specially designed switchable control architecture.Linear/constant acceleration approximation is used for attitude control, which aims to get quick response andprevent overshooting at the same time. Special proportion integral derivative (PID) controller with anti-torquecounteraction is proposed to generate servo angles. Experimental results verify the effectiveness of the proposedcontrol method.
