The Application of Lead Networks and Sinusoidal Analysis to Automatic Control Systems

Design considerations relating to the construction of a high performance servomechanism are discussed here. In particular, the improvement in performance that may be achieved through the use of lead networks* and the valuable guides to system synthesis afforded by sinusoidal analysis

are demonstrated. Direct reference to an armature-controlled d-c motor system** designed by the author is made and its dynamic characteristics are considered in detail in order to show the correlation between theory and practice as applied to a servomechanism design.
