Predicting the performance of a wind tunnel regulating system using an analog computer

THE USE of an analog computer, particularly one of the electronic differential analyzer type, in the analysis and design of feedback control systems has been well established in the past few years. Quite often, however, a detailed computer investigation of a control system is not necessary. For example, in some instances the control system may contain only a few components which can be represented by linear transfer functions, in which case the familiar methods of linear servomechanism analysis may be employed. It is also possible in some cases that it is just as economical to optimize a design on the test floor without benefit of a computer study.
