Abstract

The ultrasonic motor (USM) is expected to be applicable to various fields, but it is difficult to precisely control the USM as it contains nonlinear properties caused by various frictions, changes of temperature, fluctuation of load-mass and so on. In this research, we propose a position control method for the USM based on a 2DF (two-degrees-of-freedom) MRACS (model reference adaptive control system) with an adaptive technique to hold optimal tracking performance. The experimental results show the effectiveness of the proposed method.
