  text: An optimized control scheme for the most advanced traveling wave type ultrasonic
    motor powered by a resonant power converter is presented and verified by measurements
    on a prototype drive. Basing on an averaged drive model, which reflects the slow
    dynamic behavior of the drive's ultrasonic oscillations by time varying fundamental
    Fourier coefficients, a cascaded two-phase vector control scheme is designed.
    The novel drive control divides into an inner voltage and outer bending wave control
    compensating couplings and suppressing the beat characteristics. Since an amplitude
    modulation is applied instead of frequency modulation, the well known pull out
    phenomenon is eliminated in general. By means of an online frequency adaptation
    to the stator's resonance, the drive's performance is optimized remarkably.
