Low Authority Control of a Composite Cantilever Beam in Two Dimensions Conference Paper uri icon

abstract

  • The authors present theoretical and experimental results on active vibration control of a cantilevered S-glass composite beam using polyvinylidene (PVF2) film as a low-authority distributed control actuator. The beam is approximately 0.25 in 0.25 in 12 in with a small mass mounted at the free end. The Lyapunov stability criterion is used to derive a control algorithm for the active damper based on angular rate feedback of the free end of the beam. The algorithm is stable for all vibrational modes of the beam. Experimental results are presented which shows the increase in damping produced by the PVF2actuators for the first two modes of vibration of the beam. The damping ratio for the first mode was increased from 0.2061 to 0.6588, and the increase for the second mode was from 0.1402 to 0.5482 (with the electromagnetic excitation source oriented in the +y direction).
