Figure 5.3.6.8: Above: Flux; Below: Output voltage.
After a speed change the field current (Flux) has
some jumps. Voltage P = 10%, Voltage I = 80%.
Figure 5.3.6.9: Above: Flux; Below: Output voltage.
The gain is too low. The armature voltage increases.
Voltage P = 3%, Voltage I = 5%.
Figure 5.3.6.10: Above: Flux; Below: Output voltage.
After a short transient, the field current and armature
voltage are constant. Voltage P = 40%, Voltage I =
50%.
