Servo Motor Control System Block Diagram

Briefly a typical motor drive system is expected to have some of the systems block diagram indicated in figure 27 1.

Servo motor control system block diagram.

Field controlled dc servo motor. Block diagram of a position servo. The back emf is proportional to the speed of the motor and hence. Note the greek letter sigma meaning summation aka the controller surrounded by a circle.

They typically include a servo system that consist of feedback elements and motor driver combined in a manner. After reading this topic armature controlled dc servomotor in the control system you will understand the theory derivation expressions transfer function and block diagram. Working principle of ac servo motor. Usually the inductance of the armature winding is small and hence neglected.

This is the summation or sum point where the input signal and the. The schematic diagram of servo system for ac two phase induction motor is shown in the figure below. This will give accurate and stable control over speed and position. Below is the illustration of the various system level.

In this the reference input at which the motor shaft has to maintain at a certain position is given to the rotor of synchro generator as mechanical input theta. Below is a block diagram of a modern automated systems incorporate closed loop feedback for motion control. The load may be a conveyor system a traction system the rolls of a mill drive the cutting tool of a numerically controlled machine tool the compressor of an air conditioner a ship propulsion system a control valve for a. Let us consider the armature controlled dc servomotor as shown in figure 1.
