Paper Abstract

A theory is developed that incorporates the piezoelectric effect into slewing flexible composite materials using classical laminate theory. Using the piezoelectric material as a modal sensors allows for placement of all of the poles of the system without the need for a state observer design. Pole placement is used on a numeric example involving a graphite epoxy beam and a DC motor. Critical damping of both the motor and beam are achieved.
