6.1 Select the parameters of the PI controllers.
Realize the simulation by commanding different voltages and filed currents. Investigate the motor response.
6.2 Program the two control schemes of separately excited DC motors, with linear and with non-linear control approaches in one Simulink file. This will give you the possibility for comparison.
6.3 Program in Simulink the multiscalar current control scheme of induction motor (hint: use the block from Figure 6.13 as an example)
