Autonomous Drone Altitude Stabilization Using PID Control

MATLAB simulation of a PID-based control system to stabilize and maintain a drone’s altitude under wind disturbances with minimal error.

This MATLAB project demonstrates the design and simulation of a PID-based altitude control system for an autonomous drone. The system maintains a desired flight altitude by dynamically adjusting thrust to counteract gravity and external wind disturbances.

The project models the vertical dynamics of a quadcopter as a second-order system, implements a tuned PID controller, and simulates real-world scenarios such as sudden gusts of wind. The code visualizes the altitude response and controller performance over time.
