In science:

It has been shown in several previous research conducted by other institution that PID based controller can be used to control small rotary wing platform. This controller is developed based on empirical approach without any mathematical model.
Automated Flight Test and System Identification for Rotary Wing Small Aerial Platform using Frequency Responses Analysis
The objective of this research is to developed a rotary wing mathematical model based on flight test, and not first principle approach. So PID based controller is the logical choice for the automated flight test. Based on empirical experience, a PID cascaded controller is implemented.
Automated Flight Test and System Identification for Rotary Wing Small Aerial Platform using Frequency Responses Analysis
The frequency response (magnitude and phase response) for each input-output pair is computed using a Chirp-Z transform in this step. This can be viewed as single-input single-output characteristic of the rotary wing platform.
