Steady-State Voltage and Current Waveforms

When the steady state is attained, you can stop the simulation and plot the current and voltage waveforms using the variables V_a and I_a sent back to the MATLAB workspace by the scope.

The DC motor current and voltage waveforms obtained at the end of the starting test are shown here:
