The paper shows the usefulness of H-infinity techniques in designing a depth-control autopilot for a submarine at periscope depth. It also shows that a significant reduction in nugatory hydroplane activity can be effected if tracking notch filters are included in the autopilot inputs to discriminate against wave frequencies. The results of simulations of a submarine at periscope depth in sea-state 5 in bow and stern seas are given. The simulation uses a full six-degrees-of-freedom nonlinear mathematical model of the submarine. Depth control is maintained using a H-infinity controller designed using a linear mathematical model of the submarine. The inputs to the controller are depth and pitch and the outputs are bow and stern hydroplane angles.
