Abstract: To solve the problems of long response time and poor dynamic performance of traditional PID control, a fuzzy PID control method is adopted to design a dynamic model of a quadcopter aircraft. Fuzzy PID control combines the advantages of fuzzy control and PID control, which can effectively improve the stability and dynamic performance of the system, accelerate the response speed of quadcopter aircraft, enhance anti-interference ability, and make the system more sensitive and reliable. A simulation of the quadrotor is carried out by simulink. The results show that fuzzy PID control can effectively control quadcopter aircraft and achieve the expected control effect.
