In practical applications, the resolution of non-resonant piezoelectric linear actuator is defined as that the piezoelectric linear actuator could output the stable minimum step size under the minimum excitation voltage. As previously stated in this paper, non-uniform spacing of the threshold vector can achieve better modeling accuracy. Piezoelectric programmable shims differ from traditional piezoelectric actuators because their length can be changed by a programming device.

Piezo Direct is dedicated to providing top of the line custom piezo manufacturing. For the rate-dependent hysteresis model, experimental results show that the modeling accuracy is high in the frequency range of 20 Hz. When the PEA moves very slowly, e.g., tracking a trajectory below 1 Hz or following the trajectory of a master operator, the rate-dependence is negligible, resulting in a rate-independence (static) hysteresis.
