A new simple asymmetric hysteresis operator and its application to inverse control of piezoelectric actuators
Piezoelectric actuators (PEAs) are commonly used as micropositioning devices due to their high resolution, high stiffness, and fast frequency response. Because piezoceramic materials areExpand
