Abstract

An operator representing the inverse dynamics of hysteretic effects inherent to piezoceramic actuators is used to enhance the tracking accuracy of a piezoceramic-driven positioning system when subject to dynamic reference input signals covering a wide frequency range. An open-loop tracking controller and a closedloop tracking controller are developed based on the new inverse algorithm and are experimentally shown to achieve high-accuracy tracking control.
