Piezoelectric stack actuator parameter extraction with hysteresis compensation [PDF]

open access: yes2014 16th European Conference on Power Electronics and Applications, 2014
The Piezoelectric Actuator Drive (PAD) is a type of rotary motor that transforms the linear motion of piezoelectric stack actuators into a precise rotational motion. The very high stiffness of the actuators employed make this type of motor suited for open-loop control, but the inherent hysteresis exhibited by piezoelectric ceramics causes losses ...
