The invention relates to the technical field of helicopters, and discloses a coaxial dual-rotor helicopter rotor folding and unfolding control system, which comprises a sensor module used for sensing the position, speed, attitude and other information of rotors, including a gyroscope, an accelerometer, a barometer and the like; the flight control module is used for being responsible for controlling the whole rotor system to ensure that the stability of the helicopter is kept in the folding and unfolding process, and flight control algorithms and control laws are included; and the motor and actuator control module is used for being responsible for controlling a motor and an actuator on the rotor wing so as to realize folding and unfolding of the rotor wing. By additionally arranging the state monitoring and fault detection module, the states of all key components and sensors of the rotor wing folding and unfolding control system can be monitored in real time, and faults can be found and diagnosed in time. By detecting the fault and providing the corresponding fault information, a pilot or maintenance personnel can be helped to quickly position the problem, the fault removal time is shortened, and the reliability and safety of the system are improved.
