Step 3
Step 3
With
SGV
equal to 2, the
response is fairly well
damped (see plot).
At this point, the
SGP
should be raised again
until oscillation or
excessive overshoot
appears.
Step 4
As we iteratively increase
SGP
to 5, overshoot and
chattering becomes
significant (see plot). This
means the
SGV
gain is too
low and/or the
SGP
is too
high.
Next, we should try raising
the
SGV
gain to see if it will
dampen out the overshoot
and chattering.
Step 5
After the
SGV
gain is
raised to 5, the overshoot
was reduced but
chattering is still quite
pronounced. This means
either one or both of the
gains is too high.
The next step should be to
lower the
SGV
gain first.
