Abstract
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 between them are briefly discussed in this paper, in order to facilitate cross-literature communication about testing methodologies. To employ DSS tests, additional actuator systems and sensor devices are required, which interface the numerical and physical subsystems. However, the non-ideal actuator dynamics sometimes destabilise the test. Therefore, various modelling and control techniques are proposed in the literature to deal with DSS synchronisation control problems since 1999. The objective of this paper aims at discussing recent technical development concerning the modelling and control of DSS tests, including the following issues: parallel vs. series structures and delay differential equations vs. ordinary differential equations for DSS modelling, homogenous vs. heterogeneous concepts for dynamic analysis, and geometry-based vs. dynamics-based techniques for control development. With a series of literature review, theoretical analysis and experimental verification, the paper combines HILS with DSS and integrates their structure and control method. Then, discuss the difference between these two systems. Verify the restriction of dynamics proposed from literature by theoretical analysis and experimental application. Through the above content, this thesis will develop the theory which is more practical of engineering and experiment framework by the integration of hybrid test.
