Piezoelectric actuators exhibit limited tracking performance in precision control due to their inherent hysteresis nonlinearity. In this paper, the hysteresis behavior is described by a play operator-based Prandtl-Ishlinskii (PPI) model. And a corresponding stop operator-based Prandtl-Ishlinskii (SPI) model is utilized as a feedforward compensator for canceling the hysteresis effect in piezoelectric...
