The invention relates to an unmanned aerial vehicle flight control system having multisensor redundant backup. The unmanned aerial vehicle flight control system can be used for multi-rotor unmanned aerial vehicles, helicopters and fixed wing unmanned aerial vehicles. The system is formed by a main control unit, a coprocessor unit, a sensor redundancy unit, a data exchange unit, a data recording unit and a power supply unit. The sensor redundancy unit is formed by multi-group gyroscopes, an accelerometer, a magnetometer, a magnetometer, a barometer and a satellite positioning system. A sensor fusion technology is applied, and when failures occur to a random single sensor, the sensor can be identified and isolated without causing influence on normal work of the flight control system. According to the unmanned aerial vehicle flight control system, on the premise that the increase of the flight control weight and the cost can be ignored relative to a whole, the reliability of the flight control system is greatly improved.
