In this article, the optimal-control pilot/vehicle model is used to determine the appropriate control strategy for maintaining a STOL vehicle on the approach path in the presence of random air turbulence.Abstract:
A new technique for designing flight directors is discussed. This technique uses the optimal-control pilot/vehicle model to determine the appropriate control strategy. The dynamics of this control strategy are then incorporated into the director control laws, thereby enabling the pilot to operate at a significantly lower workload. A preliminary design of a control director for maintaining a STOL vehicle on the approach path in the presence of random air turbulence is evaluated. By selecting model parameters in terms of allowable path deviations and pilot workload levels, a set of director laws is achieved which allows improved system performance at reduced workload levels. The pilot acts essentially as a proportional controller with regard to the director signals, and control motions are compatible with those appropriate to status-only displays.read more

Effectiveness of Basic Display Augmentation in Vehicular Control by Visual Field Cues
Arthur J. Grunwald,S. J. Merhav +1 more
TL;DR: The effectiveness of different basic display augmentation concepts for remotely piloted vehicles (RPV) controlled by a vehicle mounted television camera is investigated and whether and to what extent the human operator actually utilizes the display of information representing higher order state components such as lateral velocity and acceleration.

Analytical Display Design for Flight Tasks Conducted under Instrument Meteorological Conditions
TL;DR: A relatively straightforward, nearly algorithmic procedure for deriving model-based pilot-centered display requirements is presented, and some novel applications of the optimal pilot model are discussed, including the generation of vehicle-handling-qualities levels via numerical pilot-opinion ratings.
A method for generating numerical pilot opinion ratings using the optimal pilot model
TL;DR: A method for generating numerical pilot opinion ratings using the optimal pilot model is introduced and the results indicate that the hypothesis is reasonable, but that the predictive capability of the method is a strong function of the accuracy of the pilot model itself.

Application of a Model-Based Flight Director Design Technique to a Longitudinal Hover Task
TL;DR: In this article, an analytical pilot model is used to design flight director laws for longitudinal control of a UH-1H helicopter in hovering flight in the presence of longitudinal turbulence, and the flight director is evaluated in a fixed-based pilot-in-the-loop simulation, in which root mean square performance and pilot opinion ratings are obtained.
