Abstract

Que comprende: Sistemas y metodos para compensar el control de rotacion de una cuchara excavadora. Un metodo incluye, con al menos un procesador, determinar un sentido de compensacion opuesto a un sentido de rotacion actual de la cuchara y aplicar el par de rotacion maximo disponible en el sentido de compensacion cuando una aceleracion de la cuchara es mayor que un valor de aceleracion predeterminado. El metodo tambien puede incluir determinar un estado actual de la excavadora y realizar las etapas anteriores cuando el estado actual de la excavadora es un estado de rotacion hacia el camion o un estado de vuelta a recogida. Cuando el estado actual de la excavadora es un estado de excavacion, el metodo puede incluir limitar el par de rotacion maximo disponible y permitir, con al menos un procesador, que el par de rotacion ascienda hasta el par de rotacion maximo disponible durante un periodo de tiempo predeterminado cuando la cuchara esta retraida a una posicion de avance predeterminada.
