The Application of Input Shaping to a System with Varying Parameters David P. Magee, Graduate Student Dr. Wayne J. Book, Professor George W. Woodruff School of Mechanical Engineering Georgia Institute of Technology Atlanta, Georgia The original input shaping technique developed by Singer and Seering is summarized and a different definition for residual vibration is proposed. The new definition ...

Input shaping is a method of reducing residual vibrations in computer-controlled machines. Shaped command profiles are generated by convolving a sequence of impulses, an input shaper, with the desired command signal. The shaped command profile will move the system without residual vibration. The performance of several types of input shapers is compared to the time-optimal flexible-body control ...

In the modeling of exible structures, there is generally uncertainty in both the frequencies and damping constants , and it is thus important that the control methods for such systems be robust to these uncertainties. Input shapers have been shown to yield good performance while being insensitive to modeling errors. Most previous input shaping studies, however, have addressed only frequency mod...

The emerging importance of small and medium-sized enterprises (SMEs), has led to increasing interest in recent years about how to improve their performance. Therefore, to improve SMEs’ performance, we define proactivity as an essential factor that enables a company to anticipate change, to have the desire to make a change, and to create that change in our research framework. We also suppose tha...

This paper presents an approach for designing multi-input shapers using an s-plane pole placement technique. Slightly more information about the system model is taken into account than has been traditionally done with input shaping designs. The input shaping sequences for all system inputs are solved for simultaneously , and the resulting designs lead to shorter impulse sequences than solving f...

The method of input shaping has been shown to yield good performance in the control of exible structures while being insensitive to modeling errors. However, previous studies do not take into account the distributions of the parameter variations. We develop a new input shaping method that allows the ranges of system parameter values to be weighted according to the expected modeling errors. Comp...
