AN INVESTIGATION INTO CERTAIN ASPECTS OF THE DESCRIBING FUNCTION OF A HUMAN OPERATOR CONTROLLING A SYSTEM OF ONE DEGREE OF FREEDOM,

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.
