The present paper deals with the multi-modal vibration control of CFRP laminated plates based on the independent modal space control. A modal sensor for identifying specific vibration modes is constructed by one accelerometer and band-pass filters, where the sensor is optimally placed based on the minimization criterion of observation spillover due to unmeasured vibration modes. Besides, one macro-fiber composite (MFC) actuator is also optimally placed to maximize the induced modal control forces for controlled vibration modes. The proposed optimal placement method of a sensor/actuator using satisficing trade-off method is examined through the numerical examples from the viewpoint of numerical optimization method.
