DESIGN AND IMPLEMENTATION OF PID-BASED DRONE STABILIZATION THROUGH HARDWARE-IN-THE-LOOP SIMULATION

Abstract

In recent years, unmanned aerial vehicles (UAVs), commonly known as drones, have gained significant attention due to their versatility and wide range of applications. Drones are increasingly being utilized in emergency response operations, military missions, aerial photography and filmmaking, precision agriculture, surveillance, environmental monitoring, and recreational activities. Despite their growing popularity, maintaining flight stability remains one of the most critical challenges in drone operation. Stability is disturbed due to disturbance in the form of wind storm or maybe due to nonlinearities created by mechanical changes in structure. Current research develops 3D printed drone along with hardware in loop simulation of drone to improve its disturbance rejection performance. Experimental results demonstrate that the proposed system successfully maintained stable flight and effectively compensated for disturbances under different loading conditions. The telemetry analysis confirmed satisfactory tracking performance and improved disturbance rejection capability. The findings of this study highlight the effectiveness of integrating Hardware-in-the-Loop simulation with a 3D-printed drone platform, providing a reliable and economical solution for developing robust UAV systems capable of operating in dynamic and uncertain environments.
