Mathematical models of human operators in simple two-axis manual control systems

Abstract

An application of continuous parameter optimization techniques to the synthesis of a model of human tracking behavior in a simple two-axis task is presented. Considerable emphasis is placed on the measurement of performance criteria for estimating the relative difficulty of single-axis and two-axis tasks as well as for evaluation of the validity of mathematical models. It is shown that the modeling technique can be used to yield a quantitative indication of the degree of cross coupling between axes introduced by the operator.

Analysis of delays in networked flight simulators

“…It has been shown that the human operator 1s able to use the statistical characteristics of the input signal and the dynamic characteristics of the other elements of the system to adjust (shape) his response [2][3][4][5][6][7] characteristics in order to match the behavior of the control situations [16][17][41][42][43][44].…”

“…It means that we can not extract any noise-free information from the measurements; all components of y(t) are corrupted by [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] notse. Further, it is assumed that w(t), v(t) and x(to) are independent and Gaussian with 25) and W(t) is nonnegative definite symmetric matrix.…”

“…Practically this assumption means that in the development of human performance modeling, one must provide the human operator an internal model of the system and its environment [14][15][16][17][18][19][20][21][22]. For more about human performance modeling and its role as an information processor or adaptive controller in man-machine systems, one may refer to [23][24][25][26][27][28][29][30][31][32][33][34][35][36].…”

The Pilot Influence on the Flutter Velocity of the Lightweight Plane

“…Many publications dealt with the pilot´s response to various stimuli. The focus was mainly on the pilot's response to low-frequency stimuli and traffic delays in relation to flight dynamics [1][2][3].…”

“…The accuracy of four different models is tracked. The publication [3] deals with the description of the pilot's behaviour in the system of two degrees of freedom related to longitudinal and lateral control. The experiment was performed on each axis separately, the maximum excitation frequency was about 16 Hz.…”
