Abstract

The dynamic behavior of human operators in manual control systems has long served as a compelling target for control theory explanations. While many theoretical attempts have been found wanting, some classical and modern control theory concepts have proved useful in practice. In this paper some human dynamic properties are outlined to illustrate the variety of human behavior, and some suitable theoretical treatments are summarized. Time-optimal control theory is used to characterize one form of human behavior. Other behavioral aspects are quantified by the two predominant models in current use-a structurally isomorphic cause-effect model and an algorithmic model utilizing linear-quadratic-gaussian optimal control. Many of the procedures developed to achieve practical utility for these models have parallels useful for automatic control as well.
