Ce système de commande comprend un module de puissance électrique (3), une plaque de refroidissement (2) conçue pour dissiper la chaleur provenant du module de puissance électrique (3), qui est accouplé thermiquement à la plaque de refroidissement (2), et un système de fixation pour la plaque de refroidissement (2) qui comporte plusieurs éléments espaceurs (5) destinés à espacer la plaque de refroidissement (2) de l'élément structural (4), ces éléments espaceurs (5) étant disposés de manière à réduire l'effet de la déformation de l'élément structural (4) sur la plaque de refroidissement (2). Cette invention concerne en outre un système de fixation, un ensemble compresseur (23) et un procédé pour commander un ensemble compresseur (23).
