Modeling and control of piezoelectric stack actuators with hysteresis

Piezoelectric actuators are popularly applied as actuators in high precision systems due to their small displacement resolution, fast response and simple construction. However, the hysteresis nonlinear behavior limits the dynamic modeling and tracking control of piezoelectric actuators. This thesis...

However, the hysteresis nonlinear behavior limits the dynamic modeling and tracking control of piezoelectric actuators.
