Preliminary Comparison of Hybrid Testing Techniques

Hardware-in-the-loop simulation (HILS) and dynamically substructured system (DSS) techniques are generally classified as hybrid methods for performance evaluation of engineering systems, combining both numerical simulation and hardware experiment parts. Principally, HILS techniques are widely applied to testing of power electronics and vehicle systems, while DSS methods emphasise on civil and structural engineering application. Although the two strategies are present in different fields, the similarity and difference between them are briefly discussed in this paper, in order to facilitate cross-literature communication about testing methodologies.
