An HiL-Approach for Factory Acceptance Testing of Gravimetric Dosing Systems

Based on the necessity to improve the fabrication and assembly of a gravimetric dosing system, an automated testing system, based on Hardware-in-the-Loop (HiL) simulation, has been developed to assess its Factory Acceptance Testing (FAT). The developed testing system consists of (i) a limited real-time HiL simulation and interface implemented with off-the-shelf components, (ii) a user interface for defining the test automated execution, and (iii) a verification engine for the automated collection and validation of the test. Although experimental, the adopted testing system architecture proved sufficient for the specified test procedures, while the modularity of the implementation could prove beneficial for further applications. The proposed setup is able to recreate the real system behaviour along the necessary process parameters, which was proofed by computing the correlation coefficients between real-world data and the simulation.
