Although these approaches are fundamentally different in the manner of compensation/ control, the comparative performance of the schemes has not yet been studied in simulated or real experimental tests. This paper studies the performance of these schemes via tests on a simple base-isolated structure with a natural rubber bearing.In dynamical tests, a guarantee of stability for the experimental system is essential in order to achieve a safe and reliable result. Pure time delays can be present in such experimental systems, primarily due to discrete-time computational elements, which will promote instability. This paper studies the stability of HS and DSS test systems, with a prime focus on the effect of pure time delays. In particular the schemes were applied to the substructure testing of a rubber isolation bearing, where the overall system included a digital computation time delay of r_6 ms resulting from a series of control, data acquisition and signal filter elements. Neither delay compensation nor adaptive/selftuning methods were included in these tests, in order to establish a fair and objective comparison between the basic forms of the two schemes. It was found that DSS stability was preserved in the presence of the 6 ms delay, whereas FIS was rendered unstable. This increase in robustness was due to a linear substructure controller (LSC) used in the DSS, which was based upon a knowledge of the dynamics of the transfer system and substructures.In addition, DSS exhibited significant robustness to further artificial increases in the pure time delay, eventually yielding to instability at a value of r = 17 ms. Analysis of the two schemes was found to be effective at predicting accurate stability conditions in advance of actual experimentation. (C) 2015 Elsevier Ltd.
