Piezoelectric d15shear response-based torsion actuation mechanism: an experimental benchmark and its 3D finite element simulation

“…; this can be reached indirectly via bending-twisting [1,2] or extension-twisting [3] stiffness couplings or directly through the electromechanical coupling between throughthe-thickness applied electric field and twist strains via the coupling constant d 36 [4]. However, the latter is nil for mono-morph piezoelectric materials rendering the direct twist deformation sensing or actuation non-feasible; nevertheless, this coupling can be obtained indirectly using either skewed piezoelectric polymers [5][6][7], thanks to their orthotropic piezoelectric coupling properties, or piezoceramic fiber composite actuators or sensors that were made orthotropic thanks to a suitable fiber/epoxy blend [1].…”

However, the latter effect is not exhibited by mono-morph piezoelectric materials rendering the direct torsional deformation sensing or actuation non-feasible; nevertheless, this coupling can be obtained indirectly using either skewed piezoelectric polymers (Tzou et al [13], Qiu et al [14] or Chopra [2]) due to their orthotropic piezoelectric coupling properties, or piezoceramic fiber composite actuators and sensors that were made orthotropic through a suitable fiber/epoxy blend as discussed by Aldraihem and Wetherhold [8].…”

Experimental Comparison Research on Active Vibration Control for Flexible Piezoelectric Manipulator Using Fuzzy Controller

“…There are numerous control techniques, both classical and modern, which can cope with the vibration suppression of flexible structures with piezoelectric ceramics (PZT) patches as distributed sensors and actuators [1][2][3][4][5][6][7][8][9][10][11][12]. These techniques are involved in the application of smart materials, featuring piezoelectric actuators and sensors, to the flexible structure to suppress unwanted vibration.…”

“…Fanson et al [5] presented the application of positive position feedback (PPF) control scheme to flexible piezoelectric structures. And the control algorithms of the combining of PPF and PD control and discretetime variable structure control (VSC) algorithm were experimentally used to suppress the vibration of flexible piezoelectric cantilever plate [6,7]. Dong et al [8] employed LQG algorithm and the Kalman filter identification technique to actively control piezoelectric smart structures.…”
