An analytical solution of composite beams with piezoelectric laminae is presented. The governing equation of smart laminated composite beams, which is based on first-order deformation theory (Mindlin plate theory), is derived. The main feature of this work is that it introduces the displacement potential function to simplify the governing equation. A new assumption of harmonic vibration and the transformation method of complex numbers are introduced. The behavior of feedback control gain and its control effects are studied. Graphical outputs are also generated, to study the effectiveness of piezoelectric sensors and actuators in actively controlling the transverse of smart laminated beams.
