Method for controlling fault tolerance of six-rotor aircraft

The invention belongs to the field of flight control for rotor aircrafts, and particularly relates to a method for controlling fault tolerance of a six-rotor aircraft. The method includes cutting off power supply for a single rotor if faults which stop the single rotor from rotating occur, cutting off power supply for a rotor separated from the single rotor by a 180-degree position, and simultaneously stopping outputting control signals to the two rotors; directly cutting off power supply for two rotors when faults which stop the two rotors separated from each other by a 180-degree position occur, simultaneously stopping outputting control signals to the two corresponding rotors and controlling other four rotors of the six-rotor aircraft according to layout of an 'oblique cross' four-rotor aircraft. The method has the advantages that the six-rotor aircraft can be effectively controlled under the condition that the certain system faults of the aircraft occur, accordingly, crash accidents due to the certain system faults can be prevented, and the method has a certain significance on improving the safety and the reliability of the six rotors.
