Direct Velocity Feedback for Tip Vibration Control of a Cantilever Beam with a Non-collocated Sensor and Actuator Pair
비동위치화된 센서와 액추에이터를 이용한 외팔보의 끝단 진동에 대한 직접속도 피드백제어
Abstract
This paper presents a theoretical and experimental study of a non-collocated pair of piezopolymer PVDF sensor and piezoceramic PZT actuator, which are bonded on a cantilever beam, in order to suppress unwanted vibration at the tip of the beam. The PZT actuator patch was bonded near the clamped part and the PVDF sensor, which was triangularly shaped, was bonded on the other part of the beam. This is because the triangular PVDF sensor is known that it can detect the tip velocity of a cantilever beam. Because the arrangement of the sensor and actuator pair is not collocated and overlapped each other, the pair can avoid so called 'the in-plane coupling'. The test beam is made of aluminum with the dimension of
