압전세라믹 작동기를 이용한 회전외팔보의 진동제어

초록

This paper presents active vibration control of a rotating cantilevered beam using piezoceramic actuators. After formulating the governing equation of motion, an H-infinity control which is robust to system uncertainties is synthesized through the loop shaping design procedure. Computer simulations for the steady-state vibration control are undertaken in order to demonstrate the effectiveness and robustness of the proposed control methodology.
