Section 6
An Application: A Two Quadrant DC Drive

 

 

Closed - Loop Control

This section explains how the simulation can be carried out.

Initialize_Routine:

  Set and get Parameters
  Initialize controller Outputs
  Go to Calculation_Routine

  Calculation_Routine
  Execute One_Cycle_Routine
  Plot the results

  One_Cycle_Routine
  Set angle to zero.
  For (angle= 0; angle <360o; angle +stepsize)
    {
      Set the SCR pair based on firing angle and angle.
      Go to Next_Values
    }
  Next_Values
  Calculate the increments in
  armature current
  motor speed
  tacho filter output
  speed controller output
  current controller output
  Add the increments
  Compute the firing angle

The pseudo-routine presents only the main steps.
