Description

This paper deals with a problem on the learning characteristics of human operator in a compensatory tracking control task.<br>It is already known that the human operator can learn and adapt himself to changes in control dynamics.<br>It is therefore essential for a system designer to analyze the learning behavior of the human operator. However, the process of learning has not been nivestigated in much detail. A new method to assess the learning process of a human operator is proposed here by fitting the experimental curve to logarithmic function. Variations of the coefficients are then considered to provide a measure for the learning speed.<br>The new method of evaluating the learning process is applied to the cases of step response and frequency response. Also, in order to reduce the training interval, the method of performance scores display is used for the detection of optimal switching point in a relay control system. The result of these investigations presented in this paper are expected to be of use in the design of man-machine systems.
