In this article, several modes are controlled simultaneously both in phase and amplitude on an haptic display. To achieve this, modulation/demodulation control combined with mixed spatial/frequency filters is developed. It is then applied to produce a predefined velocity field both in space and time on a plate. The experimental results show good agreement with theory. . Dans cet article, plusieurs modes sont contrôlés simultanément en phase et en amplitude sur un dispositif à retour haptique. Pour cela, un contrôle par modulation/démodulation combiné à du filtrage spatial/fréquentiel est développé. Il est ensuite appliqué pour produire un champ de vitesse prédéfini à la fois dans l’espace et dans le temps sur une plaque. Les résultats expérimentaux montrent un bon accord avec la théorie.
