Abstract :
The paper offers a general descriptive survey of position control, including the characteristics of the usual input signal and load and their effects on performance. The basic principles of automatic control are applied to unmonitored and monitored position-control systems. Displacement-displacement servo systems are dealt with in some detail, the emphasis being on electric-non-thermionic amplifiers, and electric servo motors. The performance of these systems is discussed without any analysis, but the results of analysis are used for the recommended performance.
