This is the first research on smart control and frequency analysis of a cylindrical sandwich nanoshell in framework numerical-based generalized differential quadrature method (2D-GDQM). The current nanostructure made honeycomb core piezoelectric face sheets as sensor actuator (PFSA). For modeling size-dependent nanoshell, nonlocal stress-strain gradient theory (NSGT) presented. Also, this under conveying viscous fluid, related force calculated by modified formulation Navier–Stokes. structure rotates around its axial direction. stresses strains are obtained using higher-order shear deformation (HSDT). external voltage applied to layer, Proportional-Derivative (PD) controller used for output control. Governing equations boundary conditions implementing Hamilton's principle. results show that geometry core, PD controller, velocity fluid flow, length radius ratio (L/R), have significant influence characteristics nanoshell. Another important consequence applying leads an increase critical flow nanostructure.
