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/piezoelectric strain sensor and one band-pass filter, where the sensor is optimally placed based on the minimization criterion on 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 proposed optimal placement method of sensors/actuators is examined through the numerical results from the viewpoint of numerical optimization method.
