Abstract
Digital control offers exciting possibilities for accuracy and flexibility that cannot be achieved by analog means. The USQ-20 General Purpose Digital Computer is on board several ships today for the Navy Tactical Data System, and an effort is made to show how such a computer might also be employed directly in closed-loop shipboard fire control systems. Some of the theory of sampled data systems and digital compensation is discussed. A digital computer program which simulates the action of a sampled data system with a digital controller is employed to experimentally determine the behaviour of various physical plants subject to digital control. An evaluation is made of the noise rejection capabilities, steady state error, and transient control of a digital process. A full description and instructions for its use is given for the simulator program, which has proved to be very helpful in making theoretical studies of control system behaviour.
