Robust H/sub 2/ vibration control of beams with piezoelectric sensors and actuators

Abstract

This paper studies vibration control of a beam with bonded piezoelectric sensors and actuators. Basic equations for piezoelectric sensors and actuators are presented. The equation of motion for the beam structure is derived by using the Hamilton's principle. A robust H/sub 2/ controller is designed. The numerical simulation shows that the vibration can be significantly suppressed by the proposed controller.
