摘要：

The high-performance servo control scheme using compact ultrasonic motors (USM's) as new actuators has not yet been practically realized in modern industry and office automation systems because the dynamic and steady-state modeling of USM's is almost impossible from a theoretical point of view. This paper deals with a newly proposed high-performance speed/positional servo control scheme of a traveling wave-type USM with high torque at low speed range, which is based on modern fuzzy-reasoning concepts. The new control method of the USM servo system using inverter frequency and voltage control strategies for the speed and amplitude of the traveling wave on the USM stator and the phase difference control scheme between two-phase high-frequency inverters are demonstrated and evaluated under experimental results. In particular, this USM servo control implementation based on fuzzy reasoning is successfully described from a practical viewpoint.
