Modeling and RST position controller of rotary traveling wave ultrasonic motor

Nowadays piezoelectric motors become alternative actuators to the electromagnetic motors especially for precise positioning applications. Nevertheless, suitable model as precise controller need to be developed to achieve high precision levels. This paper deal firstly with the design of an original model of the rotary ultrasonic motor USR60 from Shinsei. Secondly, the syntheses of precise RST based position controller. The performance of the model and the position controller are evaluated in the MATLAB Simulink environment.
