“…Notable examples are the work of Wasicko et al 3 that attempted to extend the principles and models introduced by McRuer et al to pursuit tracking and the many investigations into the effects of physical motion feedback on pilot behavior. [4][5][6][7][8][9] The modeling of pilot control behavior continues to receive considerable interest, due to its importance for, for example, the assessment of simulator fidelity [10][11][12] and handling qualities evaluations.…”

This paper describes an investigation into the effects of displayed error scaling on manual control behavior during compensatory roll-axis tracking. Previous experiments have indicated that for compensatory displays that, similar to an artificial horizon, present the roll tracking errors in rotational form, the deviations for typical quasi-random forcing function signals are comparatively small and difficult to perceive. This was found to lead to degraded tracking performance and lower crossover frequencies than would be expected. To investigate this, a roll-axis tracking experiment has been performed in which the scaling of the presented tracking errors was varied from 0.5 to 5 times the true tracking error. In addition, both double integrator dynamics and typical conventional roll dynamics of a small jet aircraft were considered in a mixed experimental design. The main hypothesis for this experiment was that increased scaling of the presented roll-axis tracking error would result in improved tracking performance and correlation of manual control inputs with the target forcing function signal. In addition, these effects were hypothesized to be more pronounced for the more difficult double integrator dynamics. For both controlled elements, both tracking performance and linearity of pilot control were indeed found to increase with increasing display gain, leveling of for the highest considered display gains. Further analysis of manual control behavior using McRuer et al.'s Precision Model revealed marked changes in the adopted control strategy due to changes in displayed error scaling, which were found to be highly similar for both controlled elements.

“…Pursuit tracking tasks similar to the one depicted in Fig. 1 have been studied extensively in literature, 1,12,13,16 but mainly for control tasks with quasi-random target forcing function signals (f t ) and without further external disturbances (f d ). As a continuation of previous research, 7-9 this paper addresses human control behavior for tracking tasks in which the target signal is composed of a series of discrete ramp-like changes in reference attitude and an additional quasi-random disturbance signal is present.…”

“…1,10,12,13,16 One of the reasons for this is the fact that during both pursuit tracking and control tasks where precognitive inputs are given, manual control behavior will involve responses to multiple perceived variables. This is, for instance, clear for a pursuit display configuration as presented in Fig.…”

“…This makes the modeling of such multimodal control behavior significantly more complex than the modeling of purely compensatory behavior. 12,13 For pursuit tracking, Wasicko et al 12 have shown that due to the fact that e = f t − θ, pursuit control behavior can be captured by considering only two of the three pilot responses depicted in Fig. 4(b 16 have therefore proposed to model pursuit control behavior with only the Y pt and Y pe channels depicted in Fig.…”

“…1,10,11 In addition, despite the fact that the use of a pursuit display does not preclude the adoption of pursuit behavior by a human operator, 12,13 a pursuit display in combination with ramp signals with a predictable rate of change does provide ample opportunity for pursuit tracking. On the other hand, previous experimental work has hinted at suppression of pursuit operation when an additional disturbance signal is present, 14 as disturbances on the controlled element can only be attenuated using compensatory control.…”

This paper investigates the modeling of human manual control behavior for pursuit tracking tasks in which target forcing functions consisting of multiple ramp-like changes in target attitude are used. Due to the use of a pursuit display and the predictability of such forcing function signals, it can be anticipated that a pursuit or precognitive control strategy, consisting of open-loop feedforward control inputs in response to the predictable reference signal, is applied by the human operator. If combined with an additional disturbance on the controlled element, a control task results that is similar to performing a commanded turn entry/exit or altitude capture in turbulence. It is as of yet uncertain if such pursuit or precognitive control is indeed used during such a control task, and to what extent a quasi-random disturbance would suppress pursuit/precognitive control strategies. A human-in-the-loop evaluation of the combined ramp-following and disturbance-rejection task was performed to gather data for the modeling of human manual control behavior. It is found that despite the anticipated pursuit and precognitive control inputs, classical compensatory models of human manual control dynamics are highly capable of describing human dynamics for these specific control tasks. Measured control inputs, however, are found to correspond well with proposed models for open-loop feedforward operations as well, suggesting future evaluation of a model of human behavior that combines, or switches between, error-reducing compensatory and open-loop feedforward operations.
