Paper Abstract

Ultrasonic Motors are devices with micro or even nano-positioning capabilities. This feature derives from voltage-strain characteristic of piezoelectric ceramics. Furthermore, to accomplish fine positioning, a high resolution control system is required. This paper presents simulated results from a VHDL description of a micro-positioning control system for linear traveling wave ultrasonic motors (TWUSM). The controller is dedicated to TWUSM control, and uses motor dynamic characteristics for estimating the exact slider end positioning point, from real time acquired data.
