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.

    本发明涉及直升机技术领域,公开了共轴双旋翼直升机旋翼折叠展开控制系统,包括传感器模块,用于感知旋翼的位置、速度、姿态等信息,其中包括陀螺仪、加速度计、气压计等;飞行控制模块,用于负责控制整个旋翼系统,以确保在折叠和展开过程中保持直升机的稳定性,其中包括飞行控制算法和控制律;电动机和执行器控制模块,用于负责控制旋翼上的电动机和执行器,以实现旋翼的折叠和展开。通过增设状态监测与故障检测模块,从而可以实时监测旋翼折叠展开控制系统的各个关键部件和传感器的状态,及时发现和诊断故障。通过检测故障并提供相应的故障信息,可以帮助飞行员或维修人员快速定位问题,减少故障排除时间,提高系统的可靠性和安全性。
