Research on Improved Control Algorithm of Quadrotor UAV based on Fuzzy PID

Abstract

The quadrotor UAV has received a lot of attention in various fields due to its simple structure and high reliability. In the current practical application, the quadrotor UAV mainly adopts the traditional PID control. This paper establishes a mathematical model of quadrotor UAV, combines intelligent control ideas with traditional control methods, and designs fuzzy PID (F-PID) controller and variable universe fuzzy PID (VF-PID) controller based on PID controller, to further improve the dynamic characteristics of the control system and the flight stability and robustness of quadrotor UAV. MATLAB/Simulink simulation results show that the VFPID controller has the advantages of smaller overshoot, faster regulation speed, and better robustness.
