Abstract: The paper starts from the problem of PIO (Pilot-In-the-loop Oscillations), a major problem in aircraft handling and control, where the idea of the feedback as hidden technology is basic. The real phenomenon called PIO is modeled by a feedback structure where the pilot acts as one of the components of the loop and has to be modeled accordingly. PIO are in fact self-sustained oscillations and usually are divided into three convenient categories that are based on the nature of the pilot and vehicle dynamics behavior models and analysis needed for their explanation. Category I PIO are essentially linear while Category II PIO are quasi-linear and typically associated with rate limiting. Category III PIO are fully nonlinear and non-stationary. Since PIO II are mostly tackled via various robustness approaches starting from linear models, the paper strives for a unifying approach which is illustrated accordingly.
