Reset control is concerned with how to reset a system when it is
disturbed to overcome the inherent limitations of linear feedback
control and to improve robustness. It has found applications in many
practical systems including flexible mechanical systems, tapespeed
control systems and high precision positioning systems.
This book provides an introduction to the theory of reset control, and
draws on the authors' own research and others' to explore the
application of reset control in a variety of settings, with an emphasis
on hard disk drive servo systems.
Topics covered include the motivation and basic concepts of reset
control systems; derivation of the describing function of reset systems;
how the reset matrix affects the frequency domain property of a system;
recent developments on stability analysis of reset control systems;
robust stability of reset control systems with uncertainties; reset
control systems with discrete-time reset conditions; optimal reset
control design under fixed reset time instants; and reset control
systems with conic jump sets.
This book is essential reading for researchers, postgraduates and
advanced students in control theory, and for research-based engineers
who are interested in the theory of hybrid control systems and their
engineering applications.
