Design of Vibration Control System for Liquid Tank Transfer with an Overhead Crane

Abstract

  In our previous research, a mathematical model of a rod-tank system for liquid transfer with an overhead crane was built using a double-pendulum model taking viscosity into consideration. However, since the frequency analysis of the proposed model behavior with respect to the natural frequency was insufficient, the vibration control design of the transport control system was not taken into account. In this paper, the frequency response of the derived model was analyzed, and the design of shape and size of the rod-tank system was discussed based on natural frequency. A feedforward control system using a notch-filter was also designed for reducing sloshing during liquid transfer by the overhead crane. It usefulness was clarified by simulations and experiments.
