This paper illustrates the application of sampled-data theory to the synthesis of a feedback control system using forward-path digital compensation to achieve high accuracy and fast response. It also presents a detailed description of the design and operation of a transistor system prototype. Developed for the specific purpose of controlling the position of an instantaneous portion of a cathode-ray-tube trace, the system has a number of unusual characteristics such as transport lag, digital integration, and numerous sampling rates. The practical manner in which these characteristics are implemented and the mathematical techniques used for system analysis should prove applicable to a wide variety of control-system problems.
