Capacity of Human Operator Using Smart Stick Controller
Abstract
This thesis provides an analysis of transformation rate and capacity for six subjects using the smart stick controller. The subjects were tested in both a passive and active stick mode using three different forcing functions. The smart stick controller is an aircraft stick actively controlled by an algorithm developed by the Armstrong Aerospace Medical Research Laboratory (AAMRL) at Wright-Patterson AFB, OH to improve pilot tracking performance. In the passive mode, the stick behaves as any other stick used to control aircraft. However, in the active mode, the stick exerts a force in the direction opposite to the desired motion. This thesis reviews the literature, develops and analyzes a compensatory tracking task using classical control theory, and applies information theory results to the human quasilinear model to determine the transinformation rate and capacity of the human operator. Finally, the results for both the active and passive mode are compared. Power spectral densities of the forcing functions, display error, and human response are used to calculate the human transfer function, noise remnant, transinformation rate and capacity. Keywords: Performance human, Flight control systems.
