The control system comprises: at least one linear hydraulic slide arranged within a housing of the connecting rod head, at least a first shoe arranged on a sidewall of the connecting rod head, suitable for undergoing a bearing force exerted by a controlling member, the bearing force allowing the slide to be moved, a return means for bringing the slide back to its resting position in the absence of the bearing force, At and at least a second shoe arranged on the sidewall of the connecting rod head and suitable for undergoing the bearing force.
