Abstract:In this paper, vibration suppression of an elastic beam fixed on a moving cart and carrying a concentrated or moving mass is considered. An input preshaping method with RIC (Robust Internal–loop Compensator) is proposed to suppress single mode residual vibration and to get accurate positioning of the beam–mass–cart system. The performance of the proposed input preshaping method is compared with that by previous ones by both numerical simulations and experiments.
Using the proposed method, accura… Show more
