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 controlle...
