  bibo_abstract:
  - Speed control strategies for piezoelectric drives have been presented by several
    authors. Beside various control strategies based on adaptive structures like MIAS,
    MRAS, neural nets or fuzzy control, a completely model based control system using
    an inner bending wave control and an outer speed control including a torque calculator
    for linearization has been presented. The paper deals with investigations and
    improvements of this torque calculator. The setpoint adjustment is focused to
    utilize the degrees of freedom for the bending wave values, which represents an
    additional potential for optimization of the performance of the drive system.
    Theoretical and experimental results confirm the advances.@eng
