On the Controlling of Spherical Ultrasonic Motor

Abstract:

Research team of Prof. Shigeki TOYAMA has developed at Tokyo University of A&T a new type of ultrasonic motor. Its spherical shape confer 2 or 3 degree of freedom in a single joint which makes it suitable for mechatronics field. In order to control the Spherical Ultrasonic Motor a new method by using Hall sensors and a residual magnetic field induced in rotor was implemented. Present paper is dealing with the command and the control of a SUM by using Hall elements and a residual magnetic field induced in rotor. In this way the approach of controlling problem is by using the inverse kinematics and neuronal networks.
