Abstract :
A linearized model representing the load swing dynamics of overhead cranes is considered in this paper. The model takes into account trolley motion and allows, at the same time, variations in the length of the rope carrying the load. The considered model has time-varying parameters which complicates the design problem of feedback controllers to suppress the load swing. The stability of the load swing dynamics in the presence of feedback is investigated.
