要約(日本語): Piezoelectric elements, one of the smart materials, are used as actuators and sensors. Piezoelectric elements are generally small, lightweight, and thin, making them easy to attach to structures. Therefore, they are widely used for vibration control. In this study, the locations of piezoelectric elements were determined by using homography transformation. Also, the hysteresis characteristics of the piezoelectric elements are modeled by the Prandtl-Ishlinskii (PI) model based on the play hysteresis operator. Then, a nonlinear control system is designed using operator theory. Finally, simulation of vibration control using the proposed control method is performed to demonstrate its effectiveness.
