Define servo system. Draw the block diagram of DC Servo System.
Definition: Servo system is defined as automatic feedback control system working on error signals giving the output as mechanical position, velocity or acceleration.
1) The servo system consists of error detector, amplifier, motor as controller, load whose position is to be changed. 2) DC servo system consists of potentiometer as a error detector, DC amplifier, DC motor, DC gear system and the DC load whose position is to be changed.
