SUMMARY
In our previous study (Earthquake Engineering and Structural Dynamics 2003; 32:2301), we have
developed a probabilistic algorithm for active control of structures. In the probabilistic control algorithm,
the control force is determined by the probability that the structural energy exceeds a speciÿed target
critical energy, and the direction of a control force is determined by the Lyapunov controller design
method. In this paper, an experimental veriÿcation of the proposed probabilistic control algorithm is
presented. A three-story test structure equipped with an active mass driver (AMD) has been used. The
eectiveness of the control algorithm has been examined by exciting the test structure using a sinusoidal
signal, a scaled El Centro earthquake and a broadband Gaussian white noise; and, especially, experiments
on control have been performed under dierent conditions to that of system identiÿcation in order to
prove the stability and robustness of the proposed control algorithm. The experimental results indicate
that the probabilistic control algorithm can achieve a signiÿcant response reduction under various types
of ground excitations even when the modeling error exists. Copyright ? 2004 John Wiley & Sons, Ltd.
