Effectiveness of predictive information on manual control system

Abstract

The effects of indication of predicted locus were investigated by some experiment on the preview-predictive control system in which the whole reference-route and future controled value (predicted locus) were indicated on a two-dimensional display. As a result, indication of predicted locus greatly increase control performance, but the length of predictive locus, which makes best control performance, is changed by time constant of control system. And we can express the effect of indication of predicted locus exactly by proposing following two indices; one is dial control effort to refer the difficulty of control tasks, and the other is control variation to show the subject's behavior.
