Input shaping is a simple way of reducing vibration in bridge cranes. Reduction of payload sway is particularly important if the crane must operate in a cluttered workspace or has to accurately position payloads. An input shaping controller has been implemented on a large bridge crane at the Georgia Institute of Technology. It is used to study the response(More)
Input shaping is a vibration control technique that operates by filtering reference commands so that the modified (or shaped) command does not excite the system's natural frequencies. Usually, input shaping is implemented as a filtering operation outside of any feedback loops. However, this prevents input shaping from effecting some vital control issues(More)
