Usually it is only necessary to adjust the parameters of the main
controller
Low values for P and I result in a “slower“ controller, i.e. slower
rise with set point input or larger drop in load steps. The ten-
dency to oscillation becomes smaller.
An increase in the parameters results in a “faster“ controller, e.g.
faster set point jumps, less voltage dips with load jumps. Too
much increase may lead to strong oscillation tendency or even in-
stability.

The length of the supply lines influence the control. (Additional inductance , 1m = ca.1uH)
The capacity of the load affects the control behavior
The location of the sense measurement can influence the control
