Cooperative synthesis of control and display augmentation

Abstract

The cooperative control synthesis technique, previously developed to synthesize control augmentation so as to optimize the human operator's subjective rating, is extended to the synthesis of display augmentation for closed-loop manual control tasks. The procedure allows for simultaneously augmenting the display dynamics as well as plant or controlled element dynamics via feedback, and explicitly includes task-related and pilot-centered requirements in the design objectives. Connections are made between the proposed technique and classical manual control theory, and the new methodology is demonstrated by considering a compensatory tracking task for a generic controlled element. Analytical evaluations of the various control and display augmentation results and comparisons with the results of previous experimental studies are discussed.
