A method for rudder roll stabilization having two-feedback-path nonlinear dynamic compensation (NDC) is described. The high-order, Nyquist-stable control system having NDC hereof is absolutely stable and will provide a 20%-40% improvement in performance over existing roll reduction designs when lower performance steering mechanisms are employed, and is superior to linear controllers. That is, the present invention will be effective rudder roll stabilization in commercial vessels having slower rudders as well as in vessels having steering machines representing the best performance currently available, such as military systems. Since no ship hardware modifications are required, the present roll control technology will be able to be economically implemented.
