Abstract:
A method for controlling an ultrasonic motor. From a starting velocity or starting position of the driven element, the method includes adjusting the frequency of the electrical excitation voltage such that it is equal to or close to the mechanical resonance frequency of the ultrasonic actuator; changing the frequency of the electrical excitation voltage using the signal of the velocity sensor or the position sensor towards the anti-resonance frequency of the ultrasonic actuator until an end velocity or an end position of the driven element is reached; and controlling the end velocity or position of the driven element with a predetermined accuracy by means of antiphase frequency change. Also disclosed is a corresponding control arrangement for an ultrasonic motor having an ultrasonic actuator with at least two acoustic wave generators, a driven element and a generator via a frequency adjustment.

Claim (Index 13):
The control arrangement for an ultrasonic motor (M) according to  claim 12 , wherein the control arrangement further comprises an amplitude controller ( 45 ) of the electrical excitation voltage, the input of which is connected to controller ( 38 ) for the movement velocity or the position of the driven element ( 10 ).
