Analysis and Design of Reset Control Systems

Reset control is concerned with the reset of a system, when it is disturbed, to overcome the inherent limitations of linear feedback control and improve robustness. It has found applications in many practical systems including flexible mechanical systems, tape-speed control systems, and high-precision positioning systems.This book provides a comprehensive introduction to the theory of reset control. It draws on the authors’ own research, and that of 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: Basic concepts of reset control; Robust stability; Frequency domain analysis; Reset control systems with discrete-time reset conditions; Reset control design; and Application of reset control to hard disk drive servo systems
