The methodology for designing optimal driving pattern of a moving cylindrical liquid container to reduce residual free surface oscillations after a rapid access process is presented. The control scheme proposed in this paper is based on the optimal control theory and the magnitude of control input is selected as a cost function. The effectiveness of this method is shown through experiments and simulations. In the simulations, free surface oscillations are formulated based on the finite amplitude theory and modeled as a nonlinear system with third order nonlinearity. The effect of liquid depth and the access time on the amplitude of residual surface oscillations is discussed in detail and the comparison between experimental and simulation results is performed.
