WCA: A New Efficient Nonlinear Adaptive Control Allocation for Planar Hexacopters
IEEE Access, 2023 This paper presents an efficient control allocation (CA) strategy which significantly improves the flight performance of a planar hexacopter. This allocation maps the desired control vector composed of the thrust and torques in roll, pitch, and yaw axis,
