The Options page, shown below, has selections for compensator format and
Bode diagrams.
You can make the following selections:
•
Compensator Format — Select either the time-constant format or the
zero/pole/gain format. The time-constant format is
where Tz
1
, Tz2, ..., are the zero time constants, and Tp
1
,Tp
2
, ..., are the pole
time constants.
The zero/pole/gain format is a variation on the time-constant format.
In this case, the gain is compensatorgain; 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.
