Definition of the test plan for the EMG plus the design and fabrication of the HWIL test bench are considered in this work package. This requires the EMG specifications and partial results from the EMG prototype. The HWIL testing scheme will be developed, integrating on the test bench both the control systems defined in WP5 and numerical models developed in WP2. The bench will be developed by VGA and operated by UMBRA. In parallel, BV will review all the documents and procedures to help in aligning them to the requirements of a future certification process.
