The SISO Tool page has settings for the SISO Design Tool. This figure shows
the SISO Tool page with default settings.
You can make the following selections:
•
Compensator Format — You can select either the time-constant format or
the zero/pole/gain format. The time-constant format is
where Tz
1
,Tz2,...,arethezerotimeconstants,andTp
1
,Tp
2
, ..., are the pole
time constants.
The zero/pole/gain format is a variation on the time-constant format.
In this case, thegain is compensator gain; z
1
,z
2
, ... and p
1
,p
2
, ..., are thezero
and pole locations, respectively.
•
Bode Options — By default, the SISO Design Tool shows the plant and
sensor poles and zeros as blue x’s and o’s, respectively. Uncheck this box to
eliminate the plant’s poles and zeros from the Bode plot. Note that the
compensator poles and zeros (in red) will still appear.
