Abstract: Provided is a system for controlling an RPM of a propeller and a rotor of a flight vehicle having multiple power units including: a collective pitch angle command generating unit generating a collective pitch angle command upon receiving a thrust control command from a pilot or an automatic controller; a disturbance factor compensating unit for generating an RPM compensation electronic speed control (ESC) command for compensating for an RPM error, and an electronic speed adjustment command generating unit generating a final ESC command upon receiving a collective command input or derived in the process of generating the collective pitch angle command by the collective pitch angle command generating unit and the RPM compensation ESC command generated by the disturbance factor compensating unit. RPMs of motors of a flight vehicle having a plurality of propellers and rotors may be maintained to be the same.

Abstract: The present invention relates to a control input device applicable to an eVTOL aircraft, which is an electric-powered vertical take-off and landing aircraft, and more particularly, to an aircraft control input device that may replace a cyclic control stick, a tail rotor control pedal, and a collective control stick used for flight control of a conventional aircraft, which is simpler in configuration and easier to operate than conventional control devices and may improve pilot convenience and stability of flight operation through simple and accurate flight manipulation, and a command input method using the same.
