Abstract : The present study investigates the implementation of a closed loop control in a new smart tactile stimulator called “SMARTTAC”. This haptic device is able to stimulate the fingertip in order to simulate the texture perception of different real surfaces such as gratings. Two closed loop control are implemented to ensure both a stable vibration amplitude despite of external disturbances and accurate control of the friction coefficient using the new design of the tactile stimulator. Experimental measurements give satisfactory results both on dynamics and robustness points of view.
