Abstract
A method and apparatus for controlling the relative states between a rotating load member driven by a motor via a transmission where the velocity and position of the rotating load member are determined and the velocity and position of the motor are determined. The information concerning the velocity and position of the load and motor are used by a controller to generate a torque signal for controlling the velocity and position of the motor such that there is increased relative damping and relative stiffness between the rotating load member and the motor.
