Applying short-time memory units to compensators

A COMPENSATOR is a device cascaded with a control system so that the resultant output, or controlled variable, q(t) is some function of the input, or command signal v(t) (see Fig. 1). This article suggests methods for the design of several different compensators each of which contains a short-time memory unit as an integral part of its structure. The analysis is limited to the design of linear follower-type systems in which the controlled variable is required to approximate the command signal. Although electrical terminology is employed quite frequently herein, the theory is applicable to other physical systems.
