Input shaping, a feedforward method used to reduce system vibration, typically lengthens the duration of an input command. This paper considers shaped bang-off-bang commands which do not lengthen the duration of the input command. Analytical expressions are developed to describe the vibration due to shaped commands and unshaped commands of equal length. These are then used to analyze sensitivity to parameter variation. The vibration is analyzed over a range of frequencies, damping factors, and… CONTINUE READING
