High-bandwidth nano-positioning stages (NPSs) have boosted the advancement of modern
ultra-precise, ultra-fast measurement and manufacturing technologies owing to their fast …

This paper deals with the high-precision positioning control of a dual-stage feed drive. The
design of the control system is based on the equivalent input-disturbance (EID) approach to …

By serially combining two piezoelectrically actuated compliant stages, a dual-stage fast tool
servo (FTS) is developed to greatly enhance the trajectory tracking performance of …

Repetitive control is useful if periodic disturbances or setpoints act on a control system.
Perfect (asymptotic) disturbance rejection is achieved if the period time is exactly known …

Layerwise processes are common in industrial applications and have been well-studied in
the control literature. A layerwise process has repeated layers in a spatial and/or temporal …

The dual-stage actuation effectively extends the dynamic response and tracking accuracy of
conventional fast tool servos (FTS). In this study, a normal-stressed electromagnetic stage is …

In this paper, a variable joint-velocity limits (VJVL)-constrained minimum-velocity-norm
(MVN) scheme (termed VJVL-constrained MVN scheme) is proposed and investigated for …

Control systems are usually required to track reference signals while operating under the
influence of disturbances. A fast tool servo system for noncircular machining application …

A repetitive control system (RCS) provides good control performance for periodic signals,
but it may not satisfactorily reject aperiodic disturbances. Our solution is an equivalent-input …

Introduces a revolutionary, quadratic-programming based approach to solving long-standing
problems in motion planning and control of redundant manipulators This book describes a …
