Abstract
In this brief, a strategy is proposed for the identification, starting from experimental measurements on piezoelectric actuators, of all the parameters of the recently proposed power-law hysteresis and creep model. The algorithm allows trading off modeling accuracy and speed of the inverse model (compensator) implemented in a digital device. An analysis of the relationships among parameters and their effects on modeling and circuit performances is also carried out. The proposed strategy is tested on two piezoelectric actuators, showing that the obtained models are able to fulfill the circuit specifications.
