Review of PID Controller Applications for UAVs

The roots of UAVs can be traced back to the early 20th century, marked by the development of radio-controlled aircraft during World War I. These early UAVs were primarily experimental and military-focused. The technological leaps following World War II ushered in a new era of UAVs, with the advent of reconnaissance drones. These UAVs were often used for surveillance purposes, marking the beginning of their integration into military operations [4]. The late 20th century witnessed significant strides in UAV technology, driven by advancements in computing, communication, and miniaturization. This period saw the emergence of more sophisticated UAVs with improved range, endurance, and payload capacities.
