Abstract :
An original modelling of a travelling wave ultrasonic motor is established in order to provide a new torque control law for this kind of actuator. Especially, self-control is implemented, avoiding the classical drawbacks of frequency control, that is pull-out phenomenon. With such a robust control, force feedback application is available. Experimental results are obtained on an active haptic stick.
