Power Management in Hydraulically Actuated Mobile Equipment Available to Purchase

The focus of the current paper is on the control of hydraulic systems when utilizing the advances that electronic control may bring with regard to power management, prioritized flow sharing and anti-stall, arising from being able to control both pump, valves and engine electronically. A simple model of a backhoe loader is first presented. Based on this model and the dynamic properties of the system, a generally applicable power management algorithm is developed based on an optimization procedure, which takes into account the dynamics of the system and different modes of operation and saturation. Finally the algorithm is verified through simulation results and the possibilities and limitations of the algorithm are discussed.
