The alteration of the inherent behavior of a system. As an example, ships tend to exhibit significant rolling motions at sea. To dampen these rolling motions, a roll stabilization (feedback) system can be used. Such a system consists of a set of vanes (that is, small wings) extending outward from the hull, below the waterline. By varying the vane incidence angle relative to the hull, a hydrodynamic lift is generated on the vane. The vanes are driven by a feedback system so that the rolling motions are opposed by creating positive lift on one side of the hull and negative lift on the other side.
