Abstract

Le présent système permet dobtenir une large plage de vitesses faibles et élevées, régulières et commandées avec précision, pour les caméras de surveillance à panoramique horizontal/vertical et zoom. Un moteur sans balai est commandé par un microcontrôleur en mode faible vitesse par commutation synchrone sinusoïdale, en mode vitesse élevée par commutation crénelée, et lors dune phase de transition entre le mode faible vitesse et le mode vitesse élevée, par modulation dondes carrées à modulation de largeur dimpulsion (PWM) intégrée avec des ondes sinusoïdales. Des registres de PID et de table de conversion sont utilisés par un microcontrôleur pour assurer une transition sans heurt entre le mode vitesse élevée et le mode faible vitesse, ainsi quentre le mode faible vitesse et le mode vitesse élevée, et pour bloquer la phase dune position sinusoïdale pendant les transitions, afin que la caméra de surveillance puisse passer rapidement dune cible à une autre à une vitesse pouvant atteindre 100 degrés par seconde et aussi suivre des objets qui se déplacent très lentement.
