Real-time HiL for Hydraulic Press Control Validation.

Hydraulic press control validation often competes for access time with other logistical and production needs. This can result in significant costs due to down times, longer delivery periods and sub-optimal control adjustments. Reduction of said costs has traditionally been pursued via some degree of virtual commissioning, i.e. control validation away from the press, via a model. All such models require a compromise between cost, fidelity and simulation time. Here, we present a case study in which we have achieved a low-cost, high-fidelity, real-time hydraulic press model, with a flexible methodology which allows model creation in parallel with the engineering stage, as well as easy model refinement and modification during the entire press lifecycle.
