Abstract
There is a growing interest in the use of distributed actuators and sensors for the active vibration control of thin plates. Recent efforts in this area have been resthcted to the control of plates with cantilevered boundary conditions. This paper presents an energy based analysis of distributed transducer design issues related to the observation and control of thin plates applicable to more general boundary conditions. The particular class of distributed transducers is limited to those which are separable in space and time, i.e. degenerate distributed transducers. The analysis exploits plate mode symmetry and boundary integral representations of key parameters to choose appropriate spatial weiglitings for distributed sensors and actuators. The technique may be used to simultaneously control multiple plate modes as well as target selected modes. While the results presented here are applicable to a broad class of distributed transducers, for the purposes of illustration models based on the piezoelectric polymer film polyvinylidene fluoride (PVF2) are used.
