Research on PID Quadcopter UAV Control System Based on Expert System

Quadcopter drones have many advantages and are being used more and more in various fields. This requires a stronger performance of the UAV. This paper adds an expert system algorithm on the basis of the traditional PID controller. Firstly, the kinematic modeling of the quadrotor UAV is undertaken to improve its control performance, the basic framework of the traditional PID controller is used first, and then the expert algorithm is added, and the controller parameters are adjusted through the analysis of the deviation to achieve a more accurate control effect. In this paper, the control simulation experiments of pitch angle, roll angle and yaw angle were carried out for both the traditional conventional PID controller and the optimised PID controller with additional expert algorithms, and it was shown by comparison that the expert PID controller takes less time to stabilise, has a smaller error and reduces the number of oscillations. It seems that the quadcopter UAV with expert PID control system has better control effect and stability.
