A method for generating on-off command profiles for flexible systems is presented. The command profiles move a system without residual vibration while using a specified amount of actuator fuel. Robustness to modeling errors can be incorporated into the design of the command signals. Techniques are presented that facilitate implementation and indicate prudent choices for the amount of fuel to be used. The method is compared to other command generation techniques that balance fuel usage and slew time.

Many performance measures for input shaping and command generation have appeared in the literature, but very rarely have these measures been critically evaluated or thoroughly discussed. In this paper we review and discuss a number of key measures of residual vibration. These measures are clarified, and mathematical and graphical interpretations of these measures are developed. In addition, a set of energy-based vibration measures are presented for use in even the most general situations, such as measuring the vibration of a nonlinear, multimode system in response to an arbitrary command.

And Control

This paper describes the control methods, computer simulation and experimental results on the vibration control of the loader arm which is composed of a horizontal slider and a pendulum-type arm suspended from it. In order to achieve high-speed driving and accurate positioning of the loader arm without residual vibration, one of the software-cam curves, termed the ""modified sine curve,"" was applied to drive the loader. The cam curve was described numerically on a personal computer. Three control methods together with highgain feedback control are proposed, in which the path and velocity of the slider and the swing angle of the arm are controlled according to the prescribed software curves. Experimental results show that driving of the loader with such a software curve and control of it under the limitation of the maximum swing angle of the arm are very effective for rejection of residual vibration and accurate positioning of the loader.
