15. Bump the actuator (you can use a larger bump this time) to test control
response. Figure 5-2 shows the expected response.

16. Initiate load steps on and off to confirm acceptable and stable response.
Figure 5-3 shows the expected response. Note how the fuel demand
increases/decreases quickly with negligible overshoot.
17. This usually concludes the dynamic adjustment for one set of dynamics.
These settings are typically robust. Overly aggressive adjustments should be
avoided if possible. The Reset and Compensation settings produced by this
procedure are normally not changed. Increases to the Gain may produce
some improvement in the load transient response, however Window Width
and Gain Ratio (to be described in the next few steps) may be more
effective. It is also our experience that these settings are good for rated
speed as well as idle speed. Verify this for yourself by changing to rated
speed and performing some load transients. If you feel that the response can
be improved, we recommend leaving Reset and Compensation as they are
and only adjusting Gain.
18. Repeat this procedure for other dynamic adjustment sets as considered
necessary for alternate fuel supplies or operating conditions.
