概要 | This study aims at developing a systematic approach for designing the control in-put for an overhead crane. In a previous report, numerical simulations showed that residual vibrations can be suppressed in nonlinear damped systems by elimi-nating the natural frequency component from the apparent external force, which includes the influence of the system nonlinearity and damping. This paper employs two methods to improve the robustness to the estimation error for the natural frequency. One is to increase the number of eliminated frequency compo-nents, and the other is to make the frequency derivatives of the frequency compo-nent zero at the estimated natural frequency. Numerical simulations demonstrated the effectiveness of these approaches for reducing residual vibration in overhead crane operation, showing that they exhibit similar robustness. |
