Abstract

Piezoelectric actuators (PEAs) are used in a wide variety of nano and micro positioning systems due to their remarkable features of high resolution, fast response and high load capacity. Among the non linealities existing in these actuators, the most important are hysteresis, creeping and nonlinear mechanical behaviour. In order to design an effective and robust control strategy, it is highly important to use an accurate model. In this paper it is presented an accurate amplified PEA model adjusted with experimental data. Additionally, it is designed an effective control strategy which combines inverse models for hysteresis and mechanical behaviour with a proportional-integral closed loop control.
