Analysis of Interactions between Pilot-Operator and Advanced Flight Control System

摘要

This work discusses the application of techniques use in predicting and detecting unfavorable man-machine interactions. Prediction criteria of Pilot Induced Oscillations (PIO) were applied in the designing process of experimental multi-modal fly-by-wire control system for a small light aircraft. Estimated PIO susceptibility was further verified during real-time simulations and flight tests. Verification process included subjective pilot/operator expert opinions and the results obtained from the automatic detectors, used for the PIO identification in long sets of recorded data. The general idea of the detection algorithms is based on the Fast Fourier Transform (FFT). These are presented in this paper in a form of detection applications along with the results of the flight experiments.
