Abstract
The present paper treats the single modal vibration control of CFRP laminated plates based on the independent modal space control. A modal sensor for identifying specific vibration mode is constructed by one accelerometer and one band-pass filter, where the sensor is optimally placed based on the minimization criterion of observation spillover due to unmeasured vibration modes. Moreover, one macro-fiber composite (MFC) actuator is also optimally placed to maximize the induced modal control force for controlled vibration mode. The effectiveness of optimal placement of MFC actuator for vibration suppression is examined through the experimental results.
