Description

Extremum seeking control (ESC) is used to track the maximum efficiency of the rotary ultrasonic motor. Through ESC, driving frequency is controlled to minimize induced current. "ESC data" file presents the acquired data while tracking for different preloads and driving voltage amplitudes condition. The correspondence between maximum efficiency and minimum current is presented in "Optimum Efficiency Validation" file.
