abstract

This paper presents an innovative approach towards the active vibration damping of mobile hydraulic machines. The authors’ research group recently introduced a novel control strategy based on pressure feedback and on an optimization procedure. The success of the optimization lies on the efficient quantification of the vibration extend which is the objective to be minimized. This paper addresses the definition of the objective function introducing a new method which does not require a priori knowledge of the working cycle. This approach enables the control strategy to be potentially applied to any kind of working scenario and does not require the intervention of a control designer.

The results presented in this paper show that the novel method is able to effectively attenuate the undesired oscillations while not affecting the actuator velocity.
