| Abstract |
The driving principle of travelling wave ultrasonic motors (USM) is basically different from those of electromagnetic motors and requires thus tailored control schemes. This paper deals with newly developed analog and digital
modulation concepts to drive a two-phase resonant converter, allowing a feeding of the USM with variable frequency, amplitudes and phase. A flexible experimental set-up for ultrasonic drives controlled by a DSP is presented including a suitable digital measuring system in order to realize efficiently control algorithms for the high level prototype drive. |
