Automatic Control System

An automatic control system has the following basic components: an error detector that compares the desired output to the actual output, an amplifier that increases any error signal, a controller that receives the amplified error and determines corrective action, a power actuator that implements corrective action on the system, and a sensor that provides feedback on the actual output of the system. Control of an AC servomotor is easier than an induction motor because only the control phase winding voltage needs to be controlled, not the main winding voltage. Reversing the direction of an AC servomotor can be done by interchanging the control phase winding voltage.

AUTOMATIC CONTROL SYSTEM:

The basic components of an automatic control system are error detector, amplifier and
controller, power actuator, system and sensor (or) feedback system. The block diagram of
an automatic control system is shown in figure.

Control of AC servomotor is so much easier than induction motor, because of were control only control
phase winding voltage like 12V or 24V not main winding voltage 230V AC

Direction of motor reversal is also obtained by interchanging the control phase winding voltage.
