7 Settings
We now look at the various settings that a user can access:
- Rootlocus: Set the maximum allowed gain, Kmax in rootlocus. The
rootlocus is plotted for the gain range (0,Kmax).
- Magnitude plot: Set the minimum frequency, maximum frequency and
the frequency step for the (open loop frequency) Magnitude plot. The
unit for
the frequency is rad/sec.
- Nyquist-Nichols plot: Frequency settings similar to above, for
Nyquist plot and Nichols plot.
- Bode plot: Frequency settings for the (closed loop) Bode plot.
- Dynamic response: Set the maximum simulation time and the
timestep for all dynamic responses (impulse, step, ramp, arbitrary
input, sinusoidal input).
- Sensitivity plot: Frequency settings for the sensitivity plot.
- Graphics attributes: Graphics attributes like font, colour etc
can be set from here.
- Gain configuration: Two options are possible for using rltool
(a) Gain, K, is in the forward path.
(b) Gain is in the feedback path.
The default is (a).
- Frequency units: Select either "hz" or "rad/sec". This choice is
global and affects all frequency plots.
