概要 In our previous paper, a new type of open-loop control has been proposed for suppressing the residual vibration. This control is based on the dynamical property that the residual vibration does not occur completely in a linear undamped system excited by an external force which does not contain the component of natural frequency of the system. The authors have applied this property to a nonlinear damped system and developed an efficient method to derive an adequate trajectory of the trolley which prevents the residual vibration. However, the resulting trajectory leads to a large swing of the cargo during transportation when the trolley moves quickly. This paper proposes an optimization method to design the trajectory of the trolley to minimize the angular displacement of the cargo using orthogonal polynomials for basis functions representing trolley trajectory.
