Abstract This paper concerns attitude control of a moving mass-actuated fixed-wing unmanned aerial vehicle (MFUAV). Unlike conventional roll motion UAV, which is controlled by ailerons, this MFUAV uses the movement mass block inside wing to generate moment. It difficult design suitable controller for it due strong non-linearity and coupling dynamics. Linear active disturbance rejection (LADRC) ...

This article studies the dynamics and control of a novel underactuated system, wherein a plate suspended by cables and with a freely moving mass on top, whose other ends are attached to three quadrotors, is sought to be horizontally stabilized at a certain height, with the ball positioned at the center of mass of the plate. The freely moving mass introduces a 2-degree of underactuation into the...
