An experiment Consideration on the effects of body sensory information in human control action

Abstract

This paper is concerned with the man-machine system where a human operator on a rotary chair performs compensatory tracking of the chair on both visual and body sensory informations. The machine system is consist of a rotary chair, a motor, an amplifier, and potentiomers etc. and has a second order linear transfer function.From the experimental results drawn the following inferences. (1) Visual information mainly governs the compensating operation of human when both visual and body sensory informations are available. (2) When compensating tracking by human is performed on only visual information, no significant differences on Bode diagram by individual human operators are shown. (3) When compensating operation of human is performed on only body sensory informations, the differences of individual operators are remarkable.A human operator model for this man-machine system is synthesized through some modification of the traditional P-I-D mode transfer function. The block diagram of the human operator model is drawn on the principle that both visual and body sensory informationpaths are exist, and the Bode diagram of resultant transfer function of human model well approximates that of by human operator.
