Open loop control for the tower crane whose length is time varying is proposed to reduce the residual response amplitude. Different from traveling crane, because the system is described as 2 degrees of freedom system even in the case without variation of the length, a special strategy is required in the design of the acceleration pattern for the open loop control. By introducing the nonlinear time scales, we modify the acceleration pattern in the case without time-variation of the length proposed in our pervious research. We carry out the open loop control by applying the proposed acceleration pattern. We perform the numerical simulation for the analytical model whose validity is experimentally verified. The comparison of the residual amplitude under the conventional method and the proposed method shows the effectiveness of the proposed control method for the practical use.
