ABSTRACT:
The system for stabilizing a support comprises a working rotor mounted on the support by frictionless bearings and fixed to a working member for which at least one parameter associated with the rotation of the working rotor is variable as a function of time. A nested reaction rotor is mounted concentrically relative to the working rotor by frictionless bearings such as magnetic bearings or gas bearings and it supports a reaction inertia member. A single servo-controlled electric motor is interposed between the working rotor and the reaction rotor in order to drive the working rotor and the reaction rotor in opposite directions in such a manner that the torque disturbances generated on the support by the motion of the working rotor are cancelled by the simultaneous reaction motion of the reaction rotor, with the ratio of the speeds of the working rotor and the reaction rotor being such that the total angular momentum of the working rotor and of the reaction rotor is kept equal to zero.
