In this paper, the modified independent modal space control (IMSC) algor ithm, which is a method for reducing the number of actuators, is used fo r flexible structural vibration control. By comparing the experimental r esults obtained by the IMSC and modified IMSC algorithm, the performance of those is examined. The performance of the IMSC algorithm is more eff ective than modified IMSCalgorithm 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 man y as controlled modes. For this reason, the modified IMSC algorithm is p roposed in this paper. That of the modified IMSC algorithm is similar wi th the IMSC algorithm but there are discontinuous responses because of s witching algorithm. Therefore, if the switching algorithm has gradually varying according to shape of controlforces, its performance is more e ffective and applicable than the IMSC algorithm. This paper will provide an essential experimental basis material for that study.
