MA3-6 : Reduction of Double-Pendulum Bridge Crane Oscillations
نویسندگان
چکیده
The natural sway of crane payloads is detrimental to safe and efficient operation. Under certain conditions, the problem is complicated when the payloads create a double-pendulum effect. Most crane control research to date has focused on single-mode dynamics. For example, several researchers have shown that signal-mode oscillations can be greatly reduced by properly shaping the inputs to the crane motors. This paper builds on those previous developments to create a method for suppressing double-pendulum payload oscillations. Theoretical models are initially used to develop and evaluate the input-shaping control algorithm. Then, experiments performed on a portable bridge crane are used to verify the practical effectiveness of the method.

Double-pendulum Crane Operator Performance Comparing Pd-feedback Control and Input Shaping
A primary limitation on crane operations is the difficulty of controlling payload oscillations. Given the significance of cranes, it is not surprising that a large amount of research has been dedicated to eliminating crane payload oscillation. Numerous feedbackbased control methods have been proposed. Command-shaping is another method that has received significant attention. This paper compares...
متن کاملCombined Input Shaping and Feedback Control of a Double - Pendulum System Subject to External Disturbances
A control system combining input shaping and feedback is applied to a double-pendulum bridge crane subjected to external disturbances. The external disturbances represent naturally occurring forces, such as gusting winds. The proposed control method achieves fast point-to-point response similar to open-loop input-shaping control. It also minimizes transient deflections and disturbance-induced r...

Input-shaping is a practical open-loop strategy for the control of transient and residual oscillations on cranes, especially those having predefined payload transfer paths and repeated maneuvers. In this paper double-step input-shaping control approach is developed to include maneuvers that involve large hoisting distances and speeds. The approach is based on using the graphical representation ...
