Real-time substructuring techniques are an advanced experimental method for testing large size specimens in the laboratory. In dynamic substructuring, the whole tested system is split into two linked parts, a part of particular scientific interest or nonlinearity which is tested physically, and the remaining part which is tested numerically. To achieve near-perfect synchronization of the interface response between the physical specimen and the numerical model, a good controller is needed to compensate for actuator systems dynamics, nonlinearities, uncertainties and time-varying parameters within the physical substructures. This paper presents the substructuring approach and control performance of a linear and an adaptive controller for shaking-table substructuring. Comparative tests are then performed to evaluate the performance of the controllers.
