The control of flexible systems is a large and important field of study. Unwanted transient
deflection and residual vibration are detrimental to many systems ranging from nano …

Command sha** is an important open-loop control method for improving the settling time
and positioning accuracy. This technique also minimizes residual vibrations. Shaped …

The dynamic behavior of a planar gantry crane with hoisting of the load is investigated. The
command generation method of input sha** is proposed for reduction of the residual …

Abstract Design issues, dynamic modeling, trajectory planning, and feedback control
problems are presented for robot manipulators having components with mechanical …

The rapid movement of machines is a challenging control problem because it often results in
high levels of vibration. As a result, flexible machines are typically moved relatively slowly …

Large amplitude oscillation of crane payloads is detrimental to safe and efficient operation.
Under certain conditions, the problem is compounded when the payload creates a double …

Input sha** reduces residual vibration by generating a command signal that is self
canceling. That is, any vibration caused by a portion of the command is canceled by a later …

Input sha** reduces residual vibration in computer controlled machines by convolving a
sequence of impulses with a desired system command. The resulting shaped input is then …

This paper presents a practical time-optimal and smooth trajectory planning algorithm and
then applies it to robot manipulators. The proposed algorithm uses the time-optimal theory …

In a practical application, overhead cranes are usually subjected to system parameter
uncertainties, such as uncertain payload masses, cable lengths, frictions, and external …
