This report describes the first year's work, at Webb Institute, on developing a direct digital steering system for controlling a ship model in a towing tank and evaluating different control equations and parameters. After a background discussion of automatic steering devices and principles, the model test set-up at Webb Institute, using a model of the SL-7 container ship, is described in detail. The steering gear itself is a mechanical-electrical analog of a full-scale steering gear. The automatic control is provided by a PDP-8 minicomputer, with the necessary analog-to-digital and digital-to-analog interface equipment. Results of preliminary tests are given.
