    A NEW describing-function technique is used in this paper to show the effects of several gain-controlling nonlinearities on the limit-cycle stability of an aircraft roll-stabilization system. The new method leads to a stability diagram which is divided not into the usual two regions of ¿stable¿ and ¿unstable¿ operation but rather into numerous regions each of which is associated with a particu...

    ECONOMY IS ONE of the most important considerations in the design of any system. Maximum savings can be achieved in the design of switching circuits by performing the desired logic in the simplest minimum form applicable to the equipment utilized. Boolean algebra is often used to express the functions of switching circuits and these Boolean expressions generally appear in the final form of a sum o... View full abstract»

    IN ANOTHER PAPER1 Wolf reports on the recurrence relations in the solution of a certain class of nonlinear systems. In Wolf's dissertation2 a mathematical theory for the analysis of a class of nonlinear systems has been developed. This paper reports on a stability criterion based on the aforementioned dissertation and its application to nonlinear as well as linear feedback control systems. View full abstract»

    MANY servo systems possess open-loop transfer functions which contain one or more pairs of complex conjugate poles. Often a pair of these complex conjugate poles will lie close to the imaginary axis and will cause the uncompensated system to possess a relatively poor damping ratio or damping exponent. Usually, satisfactory compensation of such systems can be achieved through the use of tachometer ... View full abstract»

    AUTOMATIC FEEDBACK-control system synthesis occupies a rather unique place among the various fields of engineering due to the indirectness of its approach. An antenna will be designed for a certain radiation pattern because this radiation pattern is called for in the intended application. On the other hand, a servomechanism which is destined to handle step inputs exclusively may be synthesized by ... View full abstract»

    ON december 6, 1941, the Seaboard Air Line Railroad placed in service the first segment of a major installation of a system of traffic control on its line. The segment was only 33 miles in length but it made history. It was a portion of a 65-mile segment of railroad to be electrically controlled from a remote location 157 miles from the most distant point. At that time this line became the longest...

    THE HISTORY of the United States shows in some degree a direct relationship between the country's progress and the building of the railroads. One of the railroads' most outstanding achievements was the phenomenal manner in which they handled more than 90% of all personnel and materials that were moved for military purposes during World War II. One objective of this paper is to show how the central... View full abstract»
