HUMAN OPERATOR CONTROL SYSTEMS: I. THE INTERACTION BETWEEN MODES OF INFORMATION DISPLAY AND CONTROL SYSTEM DYNAMICS WITH A SINE WAVE COURSE,

Abstract : Nine skilled subjects performed a one-dimensional tracking task in which the forcing function was a sine wave course. The experimental conditions were formed from combinations of following and compensatory modes of information display with position, rate, and acceleration control system dynamics. Principle measures obtained were Average Absolute Error, Root Mean Square Error, and Time-on-Target. A significant interaction was found indicating that display modes and control system dynamics were functionally interdependent. It was determined that a description of the relation between display modes and control dynamics is not complete unless it is recognized that different trends in system performance are obtained for individual subjects.
