Abstract

Systems and methods relate to a vehicle, such as a vertical takeoff and landing (VTOL) platform, which can include a stator and a rotor magnetically levitated by the stator. The rotor and stator can be annular, such that the rotor rotates about a rotational axis. The stator can include magnets that provide guidance, levitation, and drive forces to drive the rotor, as well as to control operation of rotor blades of the rotor that can be independently rotated to specific pitch angles to control at least one of lift, pitch, roll, or yaw of the VTOL platform. Various controllers can be used to enable independent and redundant control of components of the VTOL platform. One or more processors can determine an adjusted target pitch angle for a rotor blade and cause the rotor blade to rotate to the adjusted target pitch angle.
