Abstract
The various embodiments of the present disclosure relate generally to crane control systems. An exemplary embodiment of the present invention provides a crane control system comprising a real-time position-location module, an on-off controller module, and an input-shaper module. The real-time position-location module generates a position signal indicative of the distance between crane trolley and a desired location of safety. The on-off controller module maps the position signal to a velocity command signal, wherein the velocity command signal comprises instructions for the crane trolley to move in a vector relative to the desired location in at least a first velocity only if the distance between the crane trolley and the desired location is greater than a cut-off threshold. The at least a first velocity is a substantially constant. The input shaper module manipulates the velocity command signal mapped by the on-off controller module to dampen payload oscillations.
