Question

What is error detector in control system?

Answer 1

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. 

Answer 2

Error detectors are used to sense and measure any errors that might occur or already persists in the control system.

• Errors are the abnormalities that occur due to the difference between the actual value and the measured value.
• Error detectors in a control system perform the crucial task to compare the reference and output signals.
• Electrical error detectors can be either ac or dc depending on the system requirements.
