In order to promote the flight autonomy of quadrotor UAV and enhance the obstacle avoidance ability of aircraft host under unmanned supervision, a trajectory tracking control system of quadrotor UAV Based on RFID technology is designed. In the working frequency band of RFID, the given control signal is modulated and processed. With the support of RFID tag identification technology, the micro quadrotor trajectory controller and the inner loop attitude controller are connected by using tag identification protocol. Through the data communication link, the transmission application electronics required for trajectory tracking control are extracted, and the hardware design of the trajectory tracking control system is completed. By using the parameter identification strategy in the power system, the physical laws related to the trajectory and attitude control are determined, and the design of the quadrotor UAV trajectory tracking control system based on RFID technology is realized. The experimental results show that, compared with the machine vision control system, the SSI obstacle avoidance index value of the control system based on RFID technology is relatively high, the global maximum value reaches 79%, and the average roll angle of the quadrotor UAV is 85 degrees, which can effectively suppress the rising trend of the roll angle of the quadrotor UAV, and enhance the obstacle avoidance ability of the aircraft host in the case of unmanned supervision.
