A simplified form of the three-degrees-of -freedom nonlinear equations of the 3000 ton Surface Effect Ship (SES) was linearized around an equilibrium point when a thruster failure or thruster reversal occured. Optimal control feedback gains were calculated with the linearized system and applied to the nonlinear system. Evaluation of this design was based upon both comparison of the real-time human operator response and additionally a state feedback design based upon a trial and error procedure.
