Because the quadrotor unmanned aerial vehicle(QUAV)adopts an underdriven and nonlinear control system,it is highly susceptible to interference from external factors during flight,which poses a great challenge to atti-tude control.Based on this,this paper constructs a quadrotor UAV attitude control method based on a double closed-loop fuzzy PID control algorithm.Firstly,the position model and attitude model of the quadrotor UAV flight control system were established,secondly,a dual closed-loop fuzzy PID controller was designed on the basis of PID control,and finally,Simulink simulation was conducted to verify its feasibility.The results show that the attitude control system designed in this paper has good rapidity,stability and robustness,which provides a good research idea for quadrotor UAV attitude control.
