Sample Velocity Loop Tuning Session
A sample velocity loop tuning session is shown in the plots that follow. To begin the
process the Velocity Loop Proportional Gain is tuned
Figure 204: Velocity Loop Step Response Velocity Feedback vs. Time Kp=500 Ki=0
VLGN = 0
Note the system has a relatively slow response. Also based the desired velocity, there is a
steady state error. In this case, the Velocity Loop Proportional Gain can be increased to
help generate a faster response.
