In this paper, an experimental investigation was carried out of the'remnant' portion of the mathematical model of the human operator, which consists of the combination of a quasilinear describing function and a remnant term.Abstract:
: An experimental investigation was carried out of the 'remnant' portion of the mathematical model of the human operator. This model consists of the combination of a quasilinear describing function and a remnant term. A single-axis tracking task, with random forcing functions and a compensatory display, was used to investigate the effect of the type of manipulator and the bandwidth of the forcing function on the remnant. Pressure and free-moving manipulator were employed with rate-control vehicle dynamics and filtered-white-noise forcing functions similar in spectral shape to those used in previous work. Data is presented which show the effects of the manipulator and of the forcing function on the describing function, on the performance measures of the system and on the power spectrum and the amplitude probability distribution of the remnant.

Investigation into Crossover Regression in Compensatory Manual Tracking Tasks
TL;DR: In this paper, the authors investigated the crossover-regression phenomenon in compensatory manual-control tasks and analyzed the adjustment, between-subject variation, and accuracy of linear human-operator models.
A dual-loop model of the human controller
TL;DR: A dual-loop model of the human controller in single-axis compensatory tracking tasks is introduced that possesses an inner-loop closure that involves feeding back that portion of controlled element output rate that is due to control activity.

TL;DR: In this paper, a fixed-base simulation was performed to identify and quantify interactions between the pilot's hand/arm neuromuscular subsystem and such features of typical modern fighter aircraft roll rate command control system mechanization as: (1) force sensing side-stick type manipulator; (2) vehicle effective role time constant; and (3) flight control system effective time delay.

Dual-Loop Model of the Human Controller
TL;DR: In this paper, a dual-loop model of human controllers in single-axis compensatory tracking tasks is introduced, where sensor inputs to the human controller are assumed to be system error and control force.
