Study of DC Servomotor Position Controller with PI Controller

AIM

To study the DC Servomotor Position Controller with PI controller using DC Position Control

Apparatus Required

  • Trainer module
  • Patch Chords
  • Motor setup
  • CRO

 

Theory

This experiment is intended to study the operation of DC Servomotor Position Controller with PI controller. Tabulate the input and output position and the maximum overshoot.

Experiment Procedure

  • Verify the connection as per the connection diagram and connection procedure.
  • Switch ON the power supply.
  • Select the mode PI control
  • Vary the set position switch and set the motor at any position.
  • Select the SPDT switch in upward direction and note the input position in the digital display.
  • Note the maximum overshoot or maximum position achieved by the motor.
  • Select the SPDT switch in downward direction and note the output position in the digital display.
  • Check all the test point waveforms.
  • View the comparator output across the terminal and GND.





  • View the MOSFET 3 and 4 trigger pulses across the terminal and GND.





  • Tabulate the input and output position and maximum overshoot in the tabular column as shown below.
