In this work, the limitations of a miniature drive concerning high dynamics with coincident high position accuracy are examined. Therefore, the entire system is considered and optimized. A complete discrete time model is developed and the maximum possible bandwidth is determined. Influencing parameters such as position evaluation, digitization of the feedback variables and digital pulse width modulation are examined. A miniature drive is developed in order to realize and verify high dynamics and position stability in sub nanometer range.
