Abstract
In this paper, the modified independent modal space control (IMSC) algorithm, which is a method for reducing the number of actuators, is used for flexible structural vibration control. By comparing the experimental results obtained by the IMSC and modified IMSC algorithm, the performance of those is examined. The performance of the IMSC algorithm is more effective than modified IMSC algorithm in the responses of PZT sensors and the input voltages to PZT actuators. But the IMSC algorithm is limited for many applications since it is needed the number of actuators as many as controlled modes. For this reason, the modified IMSC algorithm is proposed in this paper. That of the modified IMSC algorithm is similar with the IMSC algorithm but there are discontinuous responses because of switching algorithm. Therefore, if the switching algorithm has gradually varying according to shape of control forces, its performance is more effective and applicable than the IMSC algorithm. This paper will provide an essential experimental basis material for that study.
