Piezoelectric actuators are widely applied as actuators in micro/nano-positioning systems, due to its characteristic of infinitely small displacement resolution. While the tracking control accuracy of the piezoelectric actuator is limited because of their inherent hysteretic nonlinearity. This paper describes a mathematical model which could precisely compensate the hysteresis of piezoelectric actuator...
Piezoelectric actuators are widely applied as actuators in micro/nano-positioning systems, due to its characteristic of infinitely small displacement resolution. At the same time, piezoelectricity material has nonlinear hysteretic phenomena, it will induce low position precision and it also results in closed-loop controlling system instable. This paper presents a new approach for modeling hysteretic...
