Abstract : A method is proposed for the identification of the pilot's control compensation using time domain techniques. From this information we hope to infer a quadratic cost function, supported by the data, that represents a reasonable expression for the pilot's control objective in the task being performed, or an inferred piloting strategy. (Note: here we are using the term 'strategy' as synonomous with control objective, and not with control law.) The ultimate goals of this research topic include a better understanding of the fundamental piloting techniques in complex tasks, such as landing approach; the development of a metric measurable in simulations and flight test that correlate with subjective pilot opinion; and further validation of pilot models and pilot-vehicle analysis methods. Some preliminary numerical results are presented along with the methodology.
