Abstract:
The contribution presents an operation strategy for a novel valve structure for mobile
machines’ working hydraulics which combines the flexibility and energetic benefits of
individual metering with the functionality of common primary pressure compensation
(IPC). The aim is to set up a system that uses a minimal amount of sensors and simple
control algorithms. A control strategy theoretically described in /1/ is modified to
facilitate the practical implementation on a mini excavator arm as a test rig. This test rig
consists only of components that are currently common in mass production to show if it
is possible to develop a satisfyingly working individual metering system under these
economic restrictions. The control algorithm is experimentally evaluated in terms of
functionality and energy consumption. Simulations show potential for further
improvements.
