Mobile hydraulic Systems

Mobilhydraulische Systeme © LFD

In the research area „Mobile Hydraulic Systems“, the focus is on the development of suitable drive structures, control and regulation strategies as well as their implementation and testing for mobile machines. Boundary conditions such as minimal sensor technology, cost-effective solutions and high energy efficiency play just as much a role as robustness, availability and functional safety. The modelling of the drive system is the basis of the analysis and development activities in many projects and is still consistently used for control, control tests using software-in-the-loop and hardware-in-the-loop as well as for error detection.
