  Investigation on Open Loop Position Control of Amplified Piezoactuator

  By Veeresha R K, Astron Manoj Tauro, Muralidhara ., Rathnamala Rao

  Abstract: Amplified piezoelectric actuators (APAs) consist of stacked piezoelectric actuators inside a flexural mechanical amplifier which helps in amplifying the displacements of the piezostacks in static and dynamic conditions. Accounting for their precision movement and dynamic characteristics, these actuators are extensively used in micropositioning, active damping, and microactuation applications. In this paper, FEM analysis of mechanical flexural amplifier of APA230L piezoactuator was performed to estimate its stiffness in the horizontal direction …
