  Unmanned Aerial Vehicles (UAVs) have gained widespread recognition for their
diverse applications, ranging from surveillance to delivery services. Among the
various control algorithms employed to stabilize and navigate UAVs, the
Proportional-Integral-Derivative (PID) controller stands out as a classical yet
robust solution. This review provides a comprehensive examination of PID
controller applications in the context of UAVs, addressing their fundamental
principles, dynamics modeling, stability control, navigation tasks, parameter
tuning methods, challenges, and future directions.
