The design of guidance and control system of multi-rotor aircraft is the key technology to ensure the stability of inertial guidance flight of the aircraft. Aiming at the problem of poor stability of the current multi-guidance control method, a multi-rotor guidance system based on nonlinear feedback is proposed Control system design method. The system design includes two parts: control algorithm design and hardware modular design of the system. The nonlinear feedback control method is designed to improve the control quality and stability of the aircraft. The sensing system, driver module, control module Central unit and actuator module for integrated design, digital signal processor TMS320VC5509A selected as the core control chip, the system hardware and modular design and implementation. Finally, the system commissioning is carried out. The experimental results show that this system can be used for guidance control of multi-rotor aircrafts, and has better modulation and demodulation performance of control signals and better feedback tracking performance of control information, which ensures the flight stability and guidance accuracy Sex.
