Dr. Tan and Dr. Ram Iyer, Associate Professor in Department of Mathematics
and Statistics at Texas Tech University, are guest editors for a special
issue of IEEE Control Systems Magazine (February 2009) that is focused on
modeling and control hysteresis. Hysteresis is a nonlinear phenomenon
that is both intellectually stimulating and engineering-relevant, and it
arises in diverse disciplines ranging from physics to biology, from
material science to mechanics, and from electronics to economics. The
special issue is intended to expose the broader controls community to the
fascinating subject of hysteresis. It contains articles that describe
hysteresis in interesting domains, such as economic systems and soil-water
dynamics, as well as articles that explore the origin of hysteresis and
control methods for handling hysteresis.
