Abstract
THE use of the word ‘fundamentals' in the title of this book is fully justified. A careful and detailed analysis of the physical principles underlying the operation of servo-mechanisms is made, with relation, in particular, to mechanisms for position control. The mathematical treatment is, in the main, on the transient basis-that is to say, the application of a ‘step velocity' input-and deals in separate chapters with systems employing viscous output damping, error-rate damping, integral control and the various combinations of these features used in practice. It is noteworthy that the mathematical analysis is by straightforward classical methods very fully detailed, no recourse being made to operational methods or other specialized techniques. This is a valuable feature, for the presentation is, in consequence, well suited to the student with no greater mathematical background than that of the regular undergraduate course in science or engineering.
