ABSTRACT:
Disturbing forces, such as linear forces or torques, exerted on a structural member 12 of an inertially servoed structural interface placed between two assemblies are nulled by the application of a responsive corrective inertial force or torque to the structural member. The force on the structural interface is sensed by a force sensor associated with the member. In an embodiment of the present invention for nulling linear disturbing translational forces, a servo control loop 18 is responsive to a linear translational force sensor and drives a linear actuator 22 that applies a corrective inertial linear translational force to the structural member 12 so as to null the force exerted thereon. In an embodiment of the present invention for nulling torsional disturbing forces, the servo loop 18 is responsive to a torsional force sensor 44 and drives a torque motor 42 that applies a corrective inertial torsional translational force to the structural member 12 so as to null the force exerted thereon.
