Advances in numerical experimental substructuring techniques using MCS control

Full-scale dynamic testing of many large-scale civil engineering structures such as bridges and dams is, in most cases, an impossible task due to the size and complexity of the structures when compared to the testing facilities. Scaling of the structure can lead to results that require a great deal of interpretation in order to be useful. One method developed to overcome these problems is a technique called numerical-experimental substructuring. In this work, the substructuring method is applied to a simple system using the adaptive minimal control synthesis algorithm developed at the University of Bristol. Stability of the techniques using MCS is demonstrated. Results of preliminary experiments are presented along with discussion of methods proposed to overcome the effects of noise and lags.
