In the present article, vibration suppression of higher order micro sandwich beams based on modified strain gradient beam theory (MSGT) and Reddy/Timoshenko theories is developed. Three types core, including honeycomb, foam, porous for a beam, are considered. The core’s top bottom integrated by piezoelectric layers as actuator sensor, respectively. Displacement fields defined via third-order shear deformation (TSDBT) (or Reddy (RBT)) first-order (FSDBT) Timoshenko (TBT)). governing equations motion derived using MSGT to consider small-scale effect. To optimal approaches controller, state feedback designed linear quadratic regulator (LQR) in state-space form. Moreover, effect various parameters, three temperature changes, Pasternak foundation, density dimensionless cell thickness ([Formula: see text]), internal aspect ratio angles text]) porosity parameter performed active control smart beam. numerical results indicate that parameters mentioned significantly affect It found lightweight cores have more attenuation transient response faster settling time. By analyzing changes lighter it was frequency decreases increases. Also, considering time period without elastic foundation longer than when natural vice versa. occurs earlier. field beams, this theoretical investigation developed widely benchmark experimental research manufacturing process.
