In recent years, the concept of using the rudder for roll stabilization of a ship in a seaway has been investigated with good results. Such designs have been used to solve the roll problem of a ship on steady course while compensating for yaw perturbations. To complete a review of the possible design strategies to meet the specifications for this model, the effects of the feedback gains on rolling and yawing are studied in detail. Roll angle and roll rate feedback are used to control the rudder. Roll stabilization with the rudder in various sinusoidal sea states is studied by simulation on the IBM digital computer. The model used is based on the data obtained from a typical naval ship. The Root Locus method is used to design the feedback gains. The computer simulation programs are written in Digital Simulation Language (DSL/VS), are plotted as data in DISSPLA and include the effects of rudder servo nonlinearities, which seriously restrict the ability of the rudder to reduce roll.
