Step 6
Lowering the SGV gain to 3
does not help reduce the
chattering by much.
Therefore, we should
lower the SGP gain until
chattering stops.
Step 7
Chattering stops after
reducing the SGP gain to 4
However, the overshoot is
still a little too high.
The next step should be to
try raising the SGV to
damp out the overshoot.
Step 8
After raising the SGV gain
to 4, overshoot is reduced
a little, but chattering
reappears. This means the
gains are still too high.
Next, we should lower the
SGV gain until chattering
stops.
