Power System Blockset

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 menu 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 details by using the plot function.
