Dynamic Preload Control of Rotary Ultrasonic Motors Using Extremum Seeking Control
Abdullah Mustafa, Takeshi Morita (The Univ. of Tokyo) US2018-111
Abstract (in Japanese) (See Japanese page) 
(in English) Rotary ultrasonic motors (USM) can be controlled by adjusting the elliptical trajectory on the stator?s surface or by changing the preload between the rotor and the stator. Current control schemes are based upon elliptical trajectory control under a static preload for output control and efficiency optimization. However, this control scheme results in suboptimum driving efficiency or limited operating range due to the limited solution space. Preload has thus been introduced as an additional control parameter besides driving frequency to realize further optimization and expand operation range. Preload was dynamically controlled using a piezo linear actuator (PLA). Extremum seeking control (ESC) technique was used to track the optimum driving frequency while the PID controller was utilized for dynamic preload control to realize the desired output. Experimental results have proven the effectiveness of the proposed scheme at efficiency optimization for wide operating range.
