Sampled-data control system transient analysis

IN MOST PRACTICAL situations involving sampled-data control systems, the designer has found it expedient to resort to analogue computer studies in order to determine how the transient response depends upon such factors as the sampling frequency or the velocity constant of the proposed system. The purpose of this article is to furnish a set of dimensionless curves, based upon computer studies, which are of a sufficiently generalized nature to permit approximate design criteria to be established for a wide variety of system transfer functions.
