Simulation of the DC Drive

Run the simulation by selecting Start from the Simulation menu in Simulink. Set the simulation parameters in the Simulation parameters dialog as follows.

• Simulation time: Start Time:0, Stop time: 1.2
  Solver Type: Variable-step ode23tb (stiff/TR-BDF2)
  Max Step Size: auto
  Initial Step Size: auto
  Relative Tolerance: 1e-3
  Absolute Tolerance: 1e-3
  

The motor voltage, current waveforms, and motor speed are displayed on three axes of the scope connected to the variables V_d, I_a, and .

Once the simulation is completed, you can return to the MATLAB Command Window to examine the results with more detail by using the plot function.
