Minimizing Scanning Errors in Piezoelectric Stack-Actuated Nanopositioning Platforms
IEEE Transactions on Nanotechnology, 2008 Piezoelectric stack-actuated parallel-kinematic nanopositioning platforms are widely used in nanopositioning applications. These platforms have a dominant first resonant mode at relatively low frequencies, typically in the hundreds of hertz. Furthermore, piezoelectric stacks used for actuation have inherent nonlinearities such as hysteresis and creep ...

Mathematical modeling of a V-stack piezoelectric aileron actuation
INCAS BULLETIN, 2016 The article presents a mathematical modeling of aileron actuation that uses piezo V-shaped stacks. The aim of the actuation is the increasing of flutter speed in the context of a control law, in order to widen the flight envelope. In this way the main advantage of such a piezo actuator, the bandwidth is exploited.
