Based on a special designedhardware environment an advanced control scheme for inverter-fed travelling wave type ultrasonic motors is pre-sented. After several modelling steps, including an averaged model for the controller design, a speed control schemeis implemented 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.","lang":"eng"}],"year":1997,"conference":{"name":"IEEE Industry Applications Conference Thirty-Second IAS Annual Meeting","end_date":"1997-10-09","start_date":"1997-10-05","location":"New Orleans, LA, USA"},"_id":"3999","language":[{"iso":"eng"}],"intvolume":"         1","publication":"IAS '97.
