Summary:According to a preferred aspect of the instant invention, there is provided a system and method of robust control profile generation which suppresses one or some resonant modes in a flexible dynamic system. This robust control profile is a smooth function which can be used as a velocity profile, or as a shape filter to an arbitrary control command. The robustness can be arbitrarily improved. The robustness brings about a smoother profile. The technique can be applied to both open-loop and closed-loop systems. As a consequence of the use of the instant invention, the movement of a flexible arm that is performed according to this sort of function will be one that has minimal or reduced residual vibration after it has reached its destination.
