Servo Motor Control System Block Diagram

This will give accurate and stable control over speed and position.

Servo motor control system block diagram.

They typically include a servo system that consist of feedback elements and motor driver combined in a manner. The block diagram representation of the armature controlled dc servo motor is developed in steps. Field controlled dc servo motor. Usually the inductance of the armature winding is small and hence neglected.

The back emf is proportional to the speed of the motor and hence. 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. The field servo motor. Below is the illustration of the various system level.

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. This is the summation or sum point where the input signal and the. Block diagram of a position servo.

Briefly a typical motor drive system is expected to have some of the systems block diagram indicated in figure 27 1. Simple servo system block diagram figure 2 3 view a is a block diagram of a closed loop position servo. After reading this topic armature controlled dc servomotor in the control system you will understand the theory derivation expressions transfer function and block diagram. Let us consider the armature controlled dc servomotor as shown in figure 1.
