Rudder Roll Stabilization by Nonlinear Dynamic Compensation

UW ID: 08-094


Description of Technology
 

Rudder Roll Stabilization by Nonlinear Dynamic Compensation is a method for roll stabilization of ships using a rudder for controlling heading while simultaneously reducing rolling motion and to use the vessel’s rudder and a high-order, Nyquist-stable control system having two nonlinear dynamic compensation feedback paths for providing roll reduction without experiencing instability for such systems in the presence of either rudder angle or rudder movement rate saturation.


Applications

Rudder Roll Stabilization can be used on existing ships in order to reduce the motion on a ship’s roll axis. This technology also works when used in lower performance steering mechanisms, such as commercial boats and ships.


Features & Benefits

The technology provides up to a 20-40% improvement over current designs and is extremely stable. Because of this improvement, this technology can reduce cargo damage, improve crew effectiveness, and ease helicopter landings for pilots.
