Modeling piezoelectric actuators
IEEE/ASME Transactions on Mechatronics, 2000 The piezoelectric actuator (PEA) is a well-known device for managing extremely small displacements in the range from 10 pm to 100 /spl mu/m. When developing a control system for a piezo-actuated positioning mechanism, the actuator dynamics have to be taken into account.
