This original paper describes the review of Travelling-wave type ultrasonic motor (T-USM) and a newly-proposed speed tracking controller of T-USM on the basis of computer software-based variable-gain adjustment strategy. Its speed characteristics which is effectively capable of improving speed ripple, speed regulation and speed tracking properties are feasibly demonstrated in experiment as compared with a previously-developed fuzzy-logic speed controller of T-USM actuated servo system. It is proved that T-USM speed control scheme developed herein is practically acceptable for speed servo direct drive system.
