Energy Efficiency Enhanced Landing Strategy for Manned eVTOLs Using L<sub>1</sub> Adaptive Control

A new landing strategy is presented for manned electric vertical takeoff and landing (eVTOL) vehicles, using a roll maneuver to obtain a trajectory in the horizontal plane. This strategy rejects the altitude surging in the landing process, which is the fatal drawback of the conventional jumping stra...
