Spring 1999 Seminar Series
Since the early 1940's, considerable effort has been directed toward
developing models of human feedback control activity. While approaches
espousing psychological constructs have provided considerable insight into this
modeling activity, the control-theoretic approach has proven the most useful
for engineering analyses. Early control theoretic approaches are briefly
reviewed and more recent modeling efforts are explored. In particular, the use
of a simple, single-axis, human controller model to predict a human
controller's preference in vehicle handling qualities is demonstrated.
Idiosyncratic human control behavior such as exhibited in pilot-induced
oscillations (PIOs) is discussed and a methodology for predicting the
occurrence of PIOs is presented for vehicles described by both linear and
non-linear dynamics. Finally, the utility of employing human-controller models
in flight control system design is explored.
