Study of DC Servomotor Position Controller with P Controller

Aim

To study the DC Servomotor Position Controller with P Controller using the 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 P Controller..Note down and tabulate 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 P control mode
  • Vary the Increment and decrement switch and set the motor position at any value.
  • Select the SPDT switch in upward direction and note the input position in LCD display.
  • Switch ON the pulse release switches S. Note the maximum overshoot or maximum position achieved by the motor.
  • Select the SPDT switch in downward direction and note the output position in LCD display.
  • Check all the power circuit test point waveforms.
  • View the comparator output wave form





  • View the MOSFET 1 and 2 trigger pulses across the terminals respect GND.





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





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