Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to an ECU controller of an oil-driven direct-drive unmanned aerial vehicle. Background technique [0002] Oil-driven direct-drive UAV is a special unmanned helicopter with three or more rotor shafts. It is rotated by an electric motor on each shaft to drive the rotor, thereby generating thrust. The collective pitch of the rotors is fixed, not variable like normal helicopters. By changing the relative rotational speed between different rotors, the size of the single-axis propulsion can be changed, thereby controlling the trajectory of the aircraft. [0003] The oil-driven direct-drive UAV is controlled by the ECU controller when flying, but the ECU controller of the existing oil-driven direct-drive UAV cannot guarantee the stability of the engine speed of the oil-driven direct-drive UAV, and cannot control the oil-driven direct-drive UAV. Online management ...
