Eccentricity Compensation System (ECS) The main target of the ECS is to minimize the influence of backup rolls eccentricity disturbance in the product. ECS self adapt depending on the 1st and the 2st roll eccentricity frequency. ECS is a standalone system irrespective of the existing control system.

Non-circular grinding of backup rolls to reduce rolling

Together with roll eccentricity, this causes a beat phenomenon a long term fluctuation in the rolling force variation. The frequency of fluctuation depends on the relative positions of the key grooves and the rolling speed. Relative positions of the grooves depend on the diameters of the backup rolls in the stand.

Flight dynamics (spacecraft) Wikipedia

Spacecraft flight dynamics is the science of space vehicle performance, stability, roll and yaw, with respect to a defined frame of reference. Dynamics is the modeling of the changing position and orientation of a vehicle, in response to external forces acting on the body. The eccentricity e can then be calculated for an ellipse,
