For the “piezoelectric beam” structure with a plurality of piezoelectric ceramic sheets on the surface which are used as drivers and sensors, the frequency response function formula from the driver to the sensor is derived as a mathematical model for the piezoelectric structure design and vibration control. A method of suppressing multiple input and multiple output vibration of a piezoelectric beam on a slowly fluctuating periodic vibration environment is proposed. In the control experiment of multi-harmonic vibration suppression of two input and two output piezoelectric beams, based on the real-time frequency response matrix identification, the above control algorithm is implemented to obtain satisfactory results
