In any control system, a number of components are used to perform specific control functions. These control components are potentiometers and synchros, servo motors, gear trains, tachogenerators, magnetic amplifiers, stepper motors, various types of transducers and so on. These are described in brief in this chapter.
13.2 ERROR DETECTORS — POTENTIOMETERS AND SYNCHROS
In control systems, as you know, error detectors are used to sense and measure any error, which may occur due to the difference between the actual output and the desired output. The input level is held constant as reference input corresponding to the magnitude of the desired output. If there is any deviation of the actual output from the desired ...
