摘要

This paper considers the active fault tolerant control (FTC) for hexacopter to handle disturbance torque in yaw under a total fault in one rotor. The proposed approach is based on the reconfiguration of remaining rotors. As the system is no longer controllable in all six degrees of freedom (DOF), one dimension should be abandoned. The existing approaches usually ignore the dynamic of yaw and consider only the stabilization of position. When the hexacopter is controlled without the consideration of yaw in faulty case, a disturbance torque in yaw occurs in the transient phase and causes a large yaw rate. The FTC approach proposed in this paper is able to reduce the yaw rate effectively, and the tracking error of position is bounded. The proposed approach is demonstrated by simulation examples.
