Figure 205: Velocity Loop Step Response Velocity Feedback vs. Time Kp=1000 Ki=0
VLGN = 0
The Velocity Loop Proportional Gain has been increased in the figure above. The rise time
has been decreased. However, the system can still be enhanced by adding additional
Velocity Loop Proportional Gain. The steady state error is still present.3
Figure 206: Velocity Loop Step Response Velocity Feedback vs. Time Kp=2000 Ki=0
VLGN = 0
The Velocity Loop Proportional Gain has been increase again. The response shown is
starting to look very acceptable. However, the rise time can be improved further.
