Experimental Study on the probabilistic evaluation of control gain (2)

In this paper, the effectiveness of the control algorithm which determinines the control gain based on the probabilistic distribution of structural energy was examined exciting the test structure using a sinusoidal signal, a scaled El Centro earthquake and a broadband Gaussian white noise. Specially, in order to prove the stability and robustness of the proposed control algorithm, experiments on control had been performed under a different condition to that of system identification which was presented in the companion paper. Experimental results indicate that the probabilistic control algorithm can achieve a significant response reduction under various types of ground excitations even when the modeling error exists.
