This paper compares input shaping techniques for controlling residual vibration of flexible structures. Input shaper generates vibration-reducing shaped commands through convolution of an impulse sequence with the desired command. Both feed forward and feedback control approaches with/without input shaper for uncertain dynamical systems are investigated to evaluate the control performances. The control objective is to achieve a fast settling time and robustness to plant uncertainty, to eliminate residual vibrations. It is shown by a series of simulation that a properly designed feedback controller with input shaper performs well, as compared with open-loop controller with input shaper.
