Quadcopter following controller design and MATLAB/Simulink implementation

Target tracking in the field of quadcopters is a highly challenging and intricate research area that encompasses control algorithms, sensor data fusion, and dynamics modeling. It necessitates a comprehensive approach to ensure the quadcopter's motion trajectory is stable. This stability allows the quadcopter to carefully navigate along a predetermined route, ultimately facilitating effective target tracking. Consequently, this paper focuses on analyzing the motion principles and dynamics model of quadcopters. MATLAB is utilized to simulate the model. In particular, a cascade PID control algorithm is designed, based on the fixed height mode, to actively stabilize the quadcopter's movement. To confirm the efficacy of the proposed target following controller, a simulation model is constructed using Simulink.
